Here is the whole faq from the website.

The Site

Is this real? No. This is a collaborative writing website.

What is the Foundation? We are the last bastion of security in a world where natural laws rapidly break down. We are here to protect humanity from the things that go bump in the night, from people who wield power beyond mortal understanding. We are here to make the world a safer place. We are the holders of wonders, and the crafters of dreams. We are why the world continues. In the short form, we're a creative writing site, devoted towards horror.

What does SCP stand for? "Special Containment Procedures". We generally go with "the Foundation". It also stands for the site motto: "Secure. Contain. Protect."

How long has this site been around, anyway? Read this forum post and the site history essay for details. Basically, the original SCP (SCP-173) was written back in 2007, the first incarnation of this wiki (on editthis.info) was made in early 2008, and we moved to Wikidot in the middle of that year.

Have the owners of the wiki ever considered expanding their universe to other media (television, film, podcasts, etc.)? Ugh, yes, and if we hadn't had the idea on our own, plenty of others have mentioned it to us. Licensing is an issue; we have debates about the implications of Creative Commons almost weekly now, especially now that SCP: Containment Breach is getting so big. We honestly prefer that you didn't, at least not without contacting the authors or staff.

Should I join if I don't want to write an SCP? That depends on whether you want to vote, join in on the discussions, or edit existing articles. We've got some people who have been in chat for years, and still haven't bothered to join the site. We've also got huge fans who just don't want to actually get involved. You don't need to join to read the discussion threads, as they are now open for all to read.

Is this a roleplaying site? No. While many writers appear to have characters, or avatars on the site, these are really just characters we've created for the various stories and articles. Although many of us share common names with these characters, that's just because those are our user-names. It's easier that way, and allows for our younger members to feel safer in anonymity. A good rule of thumb is that Dr/Agent/Whatever (Name) is the character, while (Name) is the writer.

Can I roleplay anyway? Not on the main wiki. The site is out-of-character only. RPing can be done elsewhere; ask around for details.

What if I just write myself as a character? You can; it's pretty common. Keep in mind that self-inserts are automatically judged negatively until the quality of the character is established. Over the top avatars are typically not thought of very well around here anymore, in spite of whatever older material you may have read. This goes double for avatars who are supposed to be funny or awesome or your idealized self. (Google "Mary Sue", or go here - warning, TVTropes link.)

I have some really awesome art that I made, where can I post it? We have a really cool Visual Records site where you can upload art of your very own. The Visual Records wiki is currently in open registration, just hit Join in the sidebar to become a member. There are also SCP fuel images, if you want to contribute to those.

How do I get to know the SCP foundation better? Read as many SCPs and tales as you can. Seriously, that's the easiest way.

What are all those [REDACTED] and [DATA EXPUNGED] that are everywhere? They are information removed from the article, generally in order to make it scarier. While most writers know what is behind the removal, they are unwilling to tell. It's a lot worse when you have to imagine what it is. Note: Don't redact information (besides site locations) in the containment procedures. In-universe, all information in containment procedures must be available to all Foundation personnel, in case they need to contain the SCP object and these procedures are all they have.

Why does the Foundation keep this SCP around? Why don't they just destroy/kill it? Well, for starters, if you've read our motto, you know SCP stands for Secure, Contain, Protect, not Destroy, Destroy, Destroy. Most of the objects and people the Foundation houses are being kept for study, which is not at all the same as sitting on death row. Why obliterate something when you have enough resources to try to discover how it works? (That said, if we destroyed everything, we wouldn't have much of a site, would we?)

Why am I being asked for my password? No one on staff will ever ask you for your password. If you think that's what they're asking for, you might want to read again.

Well that was oddly specific. It was, wasn't it? If you never thought we wanted your password, then that isn't aimed at you. It's an incredibly weird misunderstanding that a few people get based on offsite information. That's why you don't look for advice on how to get into this wiki on other sites, guys. Just read the Join This Site page, and the Required Reading, and you'll be fine.
