Uff it is very important, you feel like you are a part of something. I was here when this was founded and i remember using to talk with the original webmaster that was called Nil and was from Spain. I dont think any original members are left?
I checked out 7 Chakras too, I actually preferred that one but both were good.
I think as far as metal goes my favourite bands are probably All That Remains, In Hearts Wake, Avenged Sevenfold and Bring Me the Horizon. (and Linkin Park and Korn if we are counting Nu Metal). I listen to a lot of rock so it'd be hard to narrow it down.
You should check out Dead Letter Circus and Karnivool.
