well it seems some daft sole has decided to spam the forum with something totally irrelevant, to the forum. wonder how they would like it if we all when and spammed them.
It is some automated bot doing it. I ended up disabling guest access and creating a "group manager" account. On the main page is the name and password to log in as the manager. Then new users can log in and create an account for themselves.
Luckily, the bots are too dumb to read the main page
