Like Apples stated, the sections can be found when you scroll down the forum board. There are various sections for your interests. If you're a casual roleplayer, advanced, even free which can vary from one-liners to paragraphs. There are arena type of roleplays which is more battle and combat, 1x1, etc. They're all pretty laid out as to what each section entails. Just browse around and you can usually find something of interest for you.

If you're looking for specific partners, I say start with the 1x1 section and work your way around. 1x1 are for what it states, rps between you and someone else. Otherwise the rest of the sections tend to be either small group or large group roleplays. 

OTHERWISE, I say read [url=https://www.roleplayerguild.com/topics/150081-a-new-users-guide-to-the-guild/ooc]this[/url].

Welcome to the guild, btw.
