Which ones are you lacking?
* Good writer
I don't think I'm that good a writer, but I've been told otherwise by some people. This is a little subjective, but I don't think I can write at the standard of this site.
* Weekly at least one article
I couldn't make an insightful article every week, but I suppose if this includes things like concert announcements or metal news in general, that wouldn't be too taxing.
* Knows good metal from dreck
I listen to some stuff that would probably earn me a curb stomp if this community met me. I started listening to metal, if you could label bands like Korn and A7X as that, about 4 years ago. My tastes have obviously evolved quite a bit since then, but remnants of that past still remain, and many bands loathed here I still don't see as being that bad, if at all. I definitely haven't been studying this music for as long as the rest of you, though. Considering that a review of Soilwork was recently released here, and justified as being a "gateway" album, I could maybe contribute something to that side of the site. (Don't get the wrong idea, I don't find any 3 of the aforementioned artists to be decent)
I'm rarely directed by anything, but if I made the commitment I'd definitely stick to it, or at least make an honest attempt.
