I have been managing Joomla sites for about 3 years now. I am currently running 4 of them. One of them is a Salmon Derby Site for a non-profit. We wanted to be able to sell derby tickets and apparel. I know its not much but I understood the complete system in 30 min. and in 2 hours I had my on-line store complete. I didn't even understand what I needed to provide to our customers. This is so intuitive and complete that I can offer much better service than I had even considered.
