Every time I try to do anything on this site I apparently lack the reputation required to do it. (Add a comment, vote up a comment that worked well for me, trying to add a tag to ask this question... basically everything I've tried to do on here thus far.)
I'd like to be able to interact in this community: how do I obtain sufficient reputation to be able to do anything? How does this system work? (At time of writing, I'm half expecting that I'm about to be told that I can't ask this question because of my lack of "reputation".)
I'm not primarily linux user and generally will be asking and responding to the baby-in-a-sandbox end of the questions spectrum.
