Mr. E,
I did see you mention this before and forgot to reply. There are a couple of problems. The amount of text data in the 19,000 posts is huge. PhpMyAdmin borks or truncates the file even when I just attempt to export or modify the forum messages table. Running something inside there would probably crash the database server or make a mess of the data.
The other alternative is to export portions of it at a time and do a search and replace of certain text and then import the fixed data. Since it is text data the problem is having a search and replace script recognize which characters are html code to be removed, and which should be left intact. I could go for string searches but that would still likely grab some things I don’t want it to.
We could just delete posts over a certain age, but I think there is much in old posts that is still valuable. I’m always open to ideas. If you have something in mind I’m not seeing, please don’t hesitate to let me know. I’d love to find an easy or automated method to clean those old posts up.
