Social intranet cloud site Bitrix24 is two years old and has over 100,000 company sign-ups. To celebrate it is giving BetaNews readers the chance to claim a free account with 15 GB of online document storage -- standard free accounts only get 5GB.

Here is how to claim yours.

You have to go to the Bitrix24.com website and enter your email address. You will then be emailed a confirmation code and link to a registration form. Down in the lower right corner of the registration form, next to the "Create" button, you will see "I have promo code", click it and enter "BETANEWS", and, after refreshing your browser, you will see the available storage jump from 5 to 15 GB.

If you've been thinking of giving Bitrix24 a try there is no better time to do it.
