Your site has a nice signature campaign, but why this thread is not so active? You should bump this thread frequently, at least once a day or just ask your campaign participant to bump this thread with some info/update about your site. Active thread + nice campaign will give better effects for your site imho.
Or I think he Can hire someone who can do all the stuffs for him like handle promotion or any other site works.talking about promotion will there be something new after this long break?
Maybe a No deposit bonus again to make your site crowded again. or Wagering competition would be cool.
