cache building... Charles started one at one point but with 6.1.0 this may no longer be an issue. Also cache builders are ..... no.. can be ..... just as rough. He never finished his. Before you spend more time on yours watch to see if there is still a need after 6.1.0 gets to more folks. Hate to see you waste time.
VB to UBB converter? Maybe. Some people have expressed a need. We'll see if time permits. At one time we had one that was custom written for someone but not polished, needed command line and was not ready for prime time. It has since been lost/forgotten/deleted and was for an early VB. Probably the table data structure has changed since then and it would need to be rewritten scratch. Time is an issue with that. With 6.1.0 in public beta and 6.2.0 on deck time is something we don't have a lot of.
