I was unaware that the Guest feature had reverted back to default, which means anyone can come in here and post unidentified. I had originally disabled this feature because I felt it was too easy to abuse, i.e. strangers coming in and causing havoc unidentified. I have seen this happen on other forums.
I am now going to turn this feature off as I originally had done.
I think when we had the site issues a couple of weeks ago was when the Guest feature reverted back to default. This is not being done for any other reason apart from the reasons I have stated above.
If Guests wish to post, they can identify themselves and become a member for free.
