So far I haven't seen any failures in the databases.
The only issue I am aware of is the 'back button' issue when posting a reply that some people have experienced. If you experience the 'Back Button' problem when trying to 'Post' a reply (as far as I know that's when that 'error' occurs for all the people who experience the problem), that may be the issue.
I have deleted posts before - but I rarely do. I did last night - Eileen posted a form - and succeeded with one - and there were a bunch of tries - so I deleted a couple of the 'empty upload posts'. I screwed up as I hit the 'edit' button of the post just above the one I really wanted to delete - and then hit the 'Delete OK?' button just as I realized what I had done.
If you remember the thread you think you responded to let me know and I'll look at it with the database tool I have. But as I said - so far the databses have checked out OK. And if I 'Move' a thread I leave a 'Marker'.
Can't think of anything else.
