I don't believe anything is "missing," Gord, and all of your posts remain in their places in the Forums
they were posted to. However, I believe the software
only accesses the last 500 posts when you click on "Find all posts by GordMay." If there is an earlier post that you wish to access, I believe a Google
search on the topic the post pertains to will find all of the relevant threads. If you can recall
the title of the thread you believe the post is in, it will speed the search, but even without that, you should be able to find the "missing" post. That has been my experience, at least.
