I too miss the "old days" when the forums where very active. A lot has changed since then, both for the company as well as the members. I'm on my iPad, so I won't do a lot of fancy UBB stuff, but I recall some polls that showed the audience demographic back then. I think the biggest change has been to the target audience. They now seem to be targeting the mobile platforms and target audience of late teen early adult who don't mind the pay as you go method of purchasing coin packs to hasten your gameplay. That makes perfect sense from a business perspective. Another big change that goes along with that audience, is moving discussion of the game(s) to dedicated pages on Facebook & Twitter. Again, with the push to mobile platforms, that makes more sense than pushing a dedicated forum.
Still, I do miss the old days, when the shout box was jumping and fan fiction submissions kept me busy.
