Welcome!
As @Smitha said, our help section is thorough and, well, helpful.
Take a look at the Guidelines, and dive right in!
The General section is for more serious, on topic stuff, Social is for lighter fare, and Meta is for Fluther-specific stuff (for example, this question will probably be moved into Meta shortly by one of our talented and longsuffering Moderators).
If there’s something in particular you’re looking for, the Search box at the top can help. Otherwise, the questions are on the page in the order they’re asked, most recent at the top.
Feel free to PM any of us for additional assistance, as we love to help. You can find the moderators here .
