You have a new Private Message

I keep getting about 5 emails a day, for the last 5 days, from a website called "findplumbinghelp.com" telling me i have a new PM. From the same person no less. I think i may have registered there long ago, but can't be sure. I am hesitant to log in to this site as it could be a way to steal my password.

What does it sound like to you guys? Or could it just be spam? I've never had anything like this happen before.

Well, if you haven't visited for a long time (and are not even sure if you have registered there at all or not), I don't know why someone should send you suddenly so many PMs, unless it's someone who is looking for new contacts or a spammer.
If I were in your situation I'd mark it as spam and wouldn't be bothered too much about it. Just my personal opinion though
