Friend and defriend at will. The worst that will happen is I'll pout privately. Also, please be aware that I've been in defriending mode myself, due to a lack of time for LJ.
I'm no longer displaying my e-mail address, but my username @livejournal.com will work.
I will usually mention it if I'm about to discuss something that I think could be highly upsetting, but that's going to be my idiosyncratic opinion and I make no promises.
