I don't like this idea. The forums should stay entirely free.
If I remember correctly, in-game ranks will be on the new forums. In my opinion, that is enough. Many forum users (including me) actually have ranks in-game. We have already helped the server. Why should we pay more than we already have just for the cooldown to be removed (let's keep it real, that's the main reason why people would buy this). Implementing this would make it seem like the owners only cares about money.
Another thing I think I've seen in an old thread a long time ago was that the new forums will have a bullet proof spam protection, so it's very likely that the cooldown will be removed anyway. I think that the profile will be quite customisable too, but I'm just guessing on this point. Here's a screenshot that we got from
@Joe Henry back in april.
BTW, why is there no "I don't want a premium feature" option in the poll?
