I have been subscribing to OSTraining Joomla Support for a couple years now. They are wonderful at answering forum questions in record time. When I saw that they were teaching Intermediate Joomla in Chicago, I asked them if I should attend. They said no because I already know everything they're teaching. (!) But they offered to give me a lifetime subscription to their services if I came to help. This is so great. I used their forum at least a dozen times in the last few days alone, and turn to them every week as a rule. This lifetime subscription will be a big help to me and all my Joomla clients.
So wish me well on this maiden journey of teaching Joomla in a classroom setting. I am so looking forward to it.
