getting into bug triage

[Lex Hider]

Hi,
Finally going to roll up my sleeves and get involved.
I currently have some time to devote to bug triage.
I currently don't have any permissions.

So what's the protocol.

Simply add comments to the existing bugs?
mail to this lists what I find so other people can can make changes?
Should I be asking for increased permissions?

I have never done any stuff with bugzilla, so it would probably be helpful to 
get stepped through my 1st change at least.

Lex.
