Thank you. I never advocated for removing Tohu's image from the site. He could still remain our mascot, but our domain name shows nothing about how it is a Lego forum (if we were going to change to a Lego fan site, which we should). I Googled "Lego Forums" and BZPower is currently on the bottom of page 3 (it may vary for other people), but that's pretty far back. No way are we going to get new members through Google searches unless we change the focus of our site.
The problem is, to me, changing the domain name makes even less sense than changing the mascot. As I said, there is reputation. Some of it may be negative, but it's impossible to have a 100% positive reputation. I can practically guarantee the estrangement of several long-time members if the name of the site is changed. I simply don't see it as a necessary change, especially since it could cause more harm than good.
Not that this site can't take a more general LEGO focus; I am in support of that. I just think it can be done just as effectively without changing a name this site has held for over a decade.
Obviously, the start would be to change the title of the page to read BZPower - LEGO News, Reference, and Discussion. (Though somehow I just noticed it already says Bionicle and LEGO News, Reference and Discussion.) Most of the changes should probably be to the front page, since that's what people first see, and thus leaves that first impression. The Bionicle images should probably be replaced with more general LEGO images, like minifigs or bricks. I wouldn't advise using anything theme-specific, since that would likely lead to needing changing once again, so something general would work best as a long-term change. As for Tohu, I'm not sure I advise for his complete removal from the front page, but having some more general LEGO things around him might minimize the overwhelmingly Bionicle impact of him.
(The front page has also looked the same the entire time I've been on this site, so it might be due for an update anyway. I don't know a lot about web design, but I've been here for almost seven years and this is the only ongoing site I've been on where the front page has remained the same throughout. Now, at the same time, if it ain't broke, don't fix it. That's a judgment for someone more experienced.)
Obviously after that, it's restructuring the forums to be more generally LEGO-friendly. Move BIONICLE-centric forums to their own little areaof the site if they're necessary, and probably remove/merge them if not. Then probably have a forum for general LEGO discussion, and a few more for the big themes, like Chima, Ninjago, and Hero Factory (and maybe some for themes that aren't about to end any time soon, like City, though that doesn't get much discussion.) The forum's design itself is pretty simple, so I can't see a lot needing to be changed as far as that goes.
Obviously, this is just my opinion, but I think that's our best bet on staying afloat as a LEGO community. We've always been a LEGO fansite, just one with a focus on Bionicle. Moving forward is just about broadening our horizons.
