I currently came across some nasty corruption and I was wanting to know how I do the following.

For members profiles that became corrupt, after going through the cleansing process I now find that the members who were corrupt now say Unregistered. Is there any way I can re-associate posts with the new member numbers of those members???

Not without rewriting each and every topic on your entire board.

That's quite obviously noa a good idea.

Ok. Thanks.
