Like Jackattack said, nobody will join. If it's in the wrong section, a mod might even delete/lock it. Somebody could also probably still your idea, because people want know about your topic. It'll just get buried by the actual RP's. I would just repost it, and improve the topic also.
It's also funny how you say, your own opinion about the mob, and then say, "Don't argue with me if you have a different opinion!" Most people wouldn't join that mob, because of your opinion. If they get that mob, they'd have to be "ugly" how you described the zombie, and "gross" like you described the spider.
Have a good day, sir/ma'am.
