I signed in and out for a few years, then got tired of it and recently left that on "invisible."

I don't care about "stalkers" and I highly doubt I'd lose touch with anyone just because I show as "invisible." In fact, I haven't. I still get and read all messages, notes and comments, and I answer every one I can. I find the site to be just as "sociable" now as it was when there was a green dot next to my name. I kinda' figure (maybe wrongly) that a red dot would stop all that.
