Basically, I'm new here and I need help with some things. Can someone give me advice about this place so I can know it a bit better?
Not much to know, it's just your ordinary forum, but it's not very active atm, more of a small community
Well, I'd recommend going to Forum Games first. It's a fun way to meet more active members. Once you've started getting to know people, an Ask Me would be recommended so others can get to know you better. You can also ask questions in other's ask mes. If you like to RP, the Everypony Theater (near the bottom of the forum main page) has all your needs. I also recommend looking at the daily Announcements for news and site information & updades. I hope you enjoy your stay and I hope this helps you out a bit. It's not that the community is small as much as the amount of people active in the community is rather small in percentage. We may not hold the populous of more popular forums but we have enough of a community that this place will not die out any time soon.
There's also a Blog section http://www.everypony.com/xfa-blog-home/ and you should also check out the chatroom http://www.everypony.com/widget-pages/Chat/ Even though we're a small well-known community doesn't mean there isn't much to know.
http://www.everypony.com/#the-library.5 I would suggest checking out this section as well, so you can discuss about the show and the characters.
