Hi Charlene,

no posts have been lost due to the various upgrades. To search for your own posts, just click on your username, on the left of your post and then on "View Forum Posts" and all your posts will be listed (when I tried it, 500 were listed). Now I can see you have actually made 821 posts so I looked in the settings and found there was a limit of 500 items. I tested what would happen if I increased that to 1000, but 500 seems to be the hard limit.

Another way of searching is to use the Advanced Search (link on top right) where you can specify your username. I just tried that and only 43 entries were found - that is strange. I tried searching for my name and it found 500 entries.

So try again and if it still does not work, I will have to rebuild the search indexes that can take a long time.
