I too got the notice from SA and I swear I thought one of the things that you had to agree to was that relationships had to be face to face, not virtual.  But today, when I was looking through the tags I noticed that one of them said "online relationship".  What say you?  Did I make a mistake?  Oh wait.  Not possible.  I never make mistakes.  I once thought I did but I was wrong.

I have not received the "special" notice on my primary account, but did on an alternate.  Oddly enough, the "alt" account is intended for research only and I don't (except for one time) use it to message or reply to messages. So I'm not sure why that account got the notice and my primary, long time premium and very active account did not.

But there is indeed a check box for "No online-only" as well as "online only" tag.

Guess the SA lawyers haven't reviewed the full inventory of tags yet.
