The topic of "Why does JavaRanch use UBB" has come up many a time. Reasons for no change seem to be as follows: 1) Has all the features we want. 2) It would be difficult to change now. Reasons for change include; 1) UBB is slow 2) UBB is inflexible I noticed that the phpBB site has tools to convert data from several forums, including UBB 6.x. It also seems to have all the features of UBB. I don't know anything about phpBB's speed, but it's in the top 10 downloads at sourceforge.net, so I assume it is constantly improving -- free of charge at that. I don't know if the JavaRanch ISP supports the necessary technologies, but if it does it might be worthwhile to experiment a little and see if phpBB is a viable alternative.
phpBB is very nice, GPL etc etc, but I think one of the underlying questions often is "If JSP/Servlets are the way forward why is JavaRanch not using that technology". If a php system was used people would still be asking a similar question. Whilst very nice, I'm not sure that phpBB offers any overwhealming advantages. Marcus
