Creative slogan
I totally get what you're trying to say there, and it's something I myself might have said once upon a time. But one of the reasons Daniel and I created Metal Academy was to create a site that's inclusive for everyone, no matter what they're into. Sure, we kind of expect that attendees will be mostly into varying sub-genres of metal (there's no clan for pop after all), but we feel like the message of inclusiveness doesn't really hold up if we're condescending to other people's tastes.
Personally, I really don't like country music, hip-hop or R&B, but if I don't want fans of those musical styles to talk shit about my passion for metal music (which they generally know next to nothing about), I really shouldn't talk shit about whatever music they're passionate about (which I very likely know next to nothing about too).
I didn't mean to get all preachy here, but I guess if there was going to be a slogan for Metal Academy, I'd want it to emphasise this inclusive aspect of what we're trying to achieve. Whether your favourite band is Incantation or Boris or Slipknot or Exodus or Blind Guardian, it doesn't matter. All metal fans are welcome here. Maybe an attendee can come up with a good slogan that represents that message.
Ben, I took some time to think of your comment about a slogan that would fit better with the site's inclusive aspect, and I just came up with I think is a better but slightly cliche slogan. I was in a "teaming with autism" webinar the other day (I have autism), and I was put into a group where we came up with a team name and logo with a "United We Stand Divided We Fall" kind of theme. Hence my idea to make this better slogan, "United We Stand for Metal"! The new slogan is in an edited version of the first post above.
I'm also not a fan of genres like country, hip-hop, or R&B, but if that's what some of my friends in the outside world are into, I'll go with it. And the band that I like from that small list of "favorite bands" is Blind Guardian, which was from my earlier epic metal taste, but I might come back to listening to that band someday, now that I'm in The Guardians. Thanks again for that clan change, Ben!
