I personally think there's just nothing more we could do considering those that aren't commenting and dropping quality posts. I did encountered some posts this week and it felt like, maybe these guys think it's more like what they do see on goal.com and many other sport news sites as such but I'm sure if any of them actually gets to read this your incubation posts for once, they'll probably change.
I believe we could hit 4000 members before the year runs out too and that would be somewhat great.
