Joomla! User Group London
Joomla! Users Group London is open to all. * Whatever your experience of Joomla! you will get something from the meetings.
We regularly have talks by the members on aspects of site building and maintaining which matter to them. We have a "clinic" where members can bring questions and seek answers. We also have a roundup of the best extensions that members have come across.
Room DCG12/1 (Or ask at Reception).
There is an excellent coffee shop, hang out area and the meetings have been taking place without a break for over a decade.
If its the Third Tuesday of the month then it must be Joomla London!
