Rick,
I thought about that, but unfortunately I found about it 10 days after I release the new forum, and now on the new database I do have many new posts, that are not on the old database, like this:
Old server = all work from 2002 until October 2007
New server = All posts from 2002 until April 2007, then from January 24 until today.

So, I do have some missing posts from April 2007 until october 2007 that are on the old database, but I'm not sure how I could 'import/merge' it on the new one.
Is that possible? merge posts?

Thank you
