Oh! That's what it is!
Don't get discouraged. Remember to always improve on your idea because they will only get better. Keep listening to positive criticism and try your best bit to let negative criticism bother you. Before you know it your rp will be off the ground.
What I did when I was new was observe how others set up their interest checks and how they built their ooc. By doing that you get an idea of what is the general accepted structure on the portal you are using. With that you will garner even more interest. Ideas are rarely bad it's all about execution and then finding the right people. And that isn't as hard as it sounds, you just need to keep improving and keep your enthusiasm up. As a GM your enthusiasm affects everyone so never get down. ^^
Edit: Also don't worry yourself over anyone seeming elitish or coming off as snobish. You are in the casual section where it's about having fun, don't let your hobby become your work. The people who try and act high and mighty in the casual section are just those that were unable to do well in the advanced section xD
