Were this possible, Frank, the question that only Jim can answer is whether there exists a software module in Jim's site software that would export such posts or threads to another piece of data base management and retrieval software that could index and manage the exported files, or if that data base software is an integral part of Jim's web site management package.

I surely do not know, nor do I know what size additional workload it would be to establish and maintain the thematic data base. That is probably the killer in this - the labor to make it happen, given that the software exists in the first place.
