OK, I've joined this one as it seems to have been the first created (based on the GID), is the only one findable through the Facebook search engine and also slightly pipped the other one on numbers when I was looking.
I also added this as a link to the front page of the ALUG wiki to help others find it.
Whilst I was there, I had to revert the front page once again because of the increasing spam problem.
Is anyone looking at tightening up the wiki to stop this hijacking of the front page? Moinmoin has something to automate the process of blacklisting spammer URLs, called AntiSpamGlobalSolution:

Although perhaps just tightening up the registration process and who can make edits might be enough ...
