Here is a few suggestions. I've been talking to some people and they all want all or most of these suggestions.
1) Could you make it so you don't have to be trusted to create posts about Grushes or Gubers. Maybe you should make it an advisory to people that maybe they shouldn't go without the trusted sign, but there is a lot of people on JSP you can trust that don't have a damn "Trusted" sign on them.
2) This is regarding the 4 hour bump rule. What... The... Hell!!! Wouldn't it be better if everyone could early bump? That way if you need to get 5 people for leech on guber or more people that you need to grush NOW then you have a better chance of getting them. But is it really worth taking the effort to make a post that needs to be filled right now but it is only showed for 5 seconds? Then you can't bump for 4 hours so your screwed. Might as well use Diablo currency.
Accually thats all I have for now. I think it would be a lot better if you could fulfill this.
