Hello and welcome to RPG, a warm and welcoming community that many souls like yourself have found while sailing the wide place called the web. Currently we have a decent range of levels: Free, Casual and Advance. Free is mostly one liners and people that enjoy quick texting rp, though there's a few that can write up a fast and mean 4-5 sentences paragraph for a scene. Casual requires at least a 5 sentence paragraph though you can write much more if you want and at a notably slower pace. I like to think of this being a happy medium between Free and Advance. Advance, one area I dwell much myself mostly because of the depth fitting my taste and ability to write up to 4-5 paragraphs, is what is considered the highest level. Mainly because many rps have a lot of rules, depth and I believe the slowest of the three. 

Each have their perks and negatives, but when you find the one you like then you'll have lots of fun. Maybe I'll see you around and lurking over one of my rps one day. So happy rp hunting! ^-^
