If you have made any posts in the past 24 hours (one day from when this new interface went live), the are not lost.... simply hiding.
In order to retain our search engine placement (all links to threads on our site), I had to reindex all the threads and posts.
In doing so, I reverted back to the database backup I made before this site went live.
I've programmed a fairly complex script that's going through every post, thread, and user (over 100,000 data elements), and cross-referencing, combinding, and sorting out everything.
The downside, is this script is probably going to take around 10-20 hours to finish (based on it's speed now), because for every element, there's a lot of computing.
Now, this means any post you made in the past day or two is not gone, but simply hidden. They'll start popping back up slowly and reappearing as the script gets to them.
Any posts you make from here on out though are fine, will stay, and everything's golden.
Sorry for the turbulance today, but we're sorting everything out, and in the end, UB will be much upgraded.
