Please note that if you recently registered to this site your user id may have been accidentally deleted.
We get over 1000 new users daily. Most are SPAMers and their posts are intercepted by our SPAM software. But their user ids clog the system so periodically we remove anyone who has not posted any messages.
Unfortunately when I did this the latest time I missed checking the box that showed me only users with no posts. I did delete some users before noticing this.
So if I deleted your id, I applogize.
