Category of the fics you won't beta: I'd prefer not to beta anything in first person.
Pairing of the fics you'd beta: Most. I'm more partial to McShep though.
Pairing of the fics you won't beta: I'd prefer not to beta any OC-centric fic or any fic that focuses a pairing with some random minor character we've only seen once. However there are always exceptions! I love character exploration fics, so if you have one of those, I'll be happy to beta it.
If not pairing oriented, character fics you'd beta: Any. I prefer Rodney centric fics, but I'm not fussy.
If not pairing oriented, character fics you won't beta: -
Type of beta you'd do: All. I'm probably best at spelling, grammar and sentence structure type betaing (i.e. copyediting). I'd think I'd be pretty good at plot betaing though. Characterisation betaing is probably my weakest point (although given that I've never betaed in this fandom before, who knows?) mostly because I tend to be more focused on plot. However, that said, if I have characterisation in mind when I start reading, undoubtedly I would pick up any flaws.
I'm Australian so please keep in mind that I may accidentally use Australian spelling when I'm editing. I'll try to keep my Word on US English though when I'm betaing.
Length of the fics you'd beta: I have a pretty quick turnaround for fics of less than 5000 words (a few days at most). For anything over 10, 000 words, I'd need at least a week or so.
