If you're wondering why "Happy International" is a top trend on Twitter today, it's because today is International Women's Day, an important day that celebrates the achievements of women everywhere. This year will be the 98th celebration of International Women's Day. And although we celebrate the advances women have made today, we are also humbled by the reminder that there is still a lot of work to be done in the realm of gender equality.

In honor of International Women's Day, Mashable has put together some important links related to women, especially women and social media. Although International Women's Day has already ended in some countries, these resources are hopefully useful at any time.

There are plenty of other social media resources out there for women. So if you have a resource or websites to share for International Women's Day, please share them in the comments.
