@N3vr3ndinBordomSo there's about three sections (save for nation/arena and others) that most people take part in.
Free, Casual, and Advanced.
In ascending orders of complexity and difficulty, free being the one that only has a few lines of text, and the roleplay flies by really quickly.
Casual is more in depth, usually taking 2-3 or more paragraphs, and having a certain amount of intricacy compared to free, where you'll be using more stuff like descriptive imagery, and other fancy language techniques. (I personally dwell here alot.)
Advanced is where the big boys play, usually pages of paragraphs are posted and this is where the most 'advanced' writers can test their craft and go into rps that require really long- and meaningful writing.
Now once you've picked one side, either find an rp on the section or look for an rp in the section's interest checks (where people post their ideas on starting an rp and see if they can gather enough 'interest'.) It is found in the subsection of each section. Refer to the picture.
I would link you some, but I think finding an rp suited for you is the best. Sorry, if this confused you.
