For what it's worth, I don't know that closing the BS section to guests would clean the place up much. There are some members who are pretty objectionable - earlier this week I received the following in a PM from a member:
Laughing my c**t out here, what the fuck could an ole c**t at your age do ? come on tell me. I have have my head in and out of that pit marked face of yours before you knew what happened. BNP ? Sorry c**t, I don't like them. I see you are on bebo and facebook, like the young ones then I take it, you should select a better picture than the one of you wearing the hat holding the doggie looks a bit dodgy, it has kiddyfiddler written all over it.
Do yourself a favour and don't cross swords with me, then again, it just might be fun to play you like a fiddle, your call you ole c**t.
The asterisks are mine, by the way. As the person in question is, shall we say, 'challenged', it's water off a duck's back, but with this sort of drivel flying into people's inboxes, the BS section looks positively peachy!
