Hello. I've seen this ad and the one over in the casual section. I don't think your idea is necessarily poor or even as unorganized as you think. But for some people you may want to offer additional clarification on certain rules and structures. Especially if you intend on pursuing this in the advanced section ( and be sure that is what you want to do because rps in this section will have certain expectations placed on them by players.) 

For example. How might things like magic work? What classes can people play and what setting might you be drawing inspiration from? Is this a D&D-esque dungeon crawl? Etc, etc.

Also don't be worried if people don't immediately flock to your post. Sometimes it takes a few days for an idea to leave the interest stage. And there are Sometimes people who are interested but are waiting to see if anyone else posts interest first.

If this is your first time on this site i reccomend sticking to the casual section. It will be eaiser on you as a DM to control and keep pace with.
