In the past before the what I think they have dubbed Guildfall, when I was more active all it meant when your interest check recieved little response was typically because the format was unappealing or the information presented was lacking. With that being said, tweak your interest check and little bit. More it to a different level of role play. Work on your presentation. I would say try it at least twice before deciding to move on to a different idea. It also helps you bump your stuff up on the list to make sure people are seeing it towards the top of the page. Sometimes people don't scroll down al that far.
