In regards to the search funtion issue, I think mrgizmow hit the nail on the head...PM a moderator or ChopperCharles with your problem or concerns to see if it can be resolved.
Not related to the search issue, but I had a different problem that was resolved by the administrator. I and another member (at least 1 other member) lost the ability to log into this site from our home computers. In my case it was only my home computer. I was able to log in as normal from any other computer, i.e. from my sons computer at his house or at my work, without any issues. The problem I and the other member had was not related to our computers, software, or internet service provider, but I believe related to IP address recognition. I PM'd a moderator with my issue. He was unable to resolve the problem, but referred me to ChopperCharles, the site administrator. I did PM ChopperCharles and within a day, I and the other member were again able to log in from our home computers. Problem resolved.
