GUEST,
for "personal message" read "private conversation".
I don't really see how that equates to abuse in the catholic church.
I don't see anything wrong with people who use the forum - whether they are guests or members - trying to make it a better place to be. I come hear to learn more about the music I love, I read postings from members and guests with equal interest, but just as I distance myself from someone abusive in a pub, I can ignore postings in the forum.
I don't always like what I read in members' contributions, but it seems more likely in my observation that obnoxious comments will come from anonymous guests.
