You know, I've technically never tried deleting it, but I haven't used Skype in months and it hasn't done anything weird or mysterious in that time. It just sits there, so quiet that sometimes I almost forget I have it. :hehe

Or at least, that's the case for my own computer. I did uninstall it off a friend's computer, once. No issues there, either. But I admit I never asked why she wanted it gone... hmm... :hmm
