I used JMS for awhile, completely to my satisfaction. It's easy to install and the tutorials are just as they should be (to the point!) - just great. Then yesterday I had a problem: JMS was gone. Now I'm the type of person that starts looking first myself - making things worse of course... It turned out that the hosting company had server problems without them knowing.
Anyway, in the meantime I had put a message on the JMS Forum. Within 10 minutes I had an answer. We mailed a couple of times and JMS gave me the right directions. Very quickly, very much to the point. Chapeau!
