I've now become a Nervous Nellie! Got a pm from someone inviting me to be a moderator on a "recovery" website. Without thinking, I clicked on the link just to check it out. It looked legitimate enough, although it appeared new with only 39 members. I didn't feel I had time to devote to it, so I tried to send a gracious declination by pm, and was told that person has "refused to accept any pm's". What the heck?
I contacted CMC for her advice. I just hope I haven't left myself open to any viruses!
