Like Don, I do not claim to be an expert at anything, nor do I expect to receive free opinions from experts when I am seeking advice on this site. Nevertheless, I have certainly received helpful advice from fellow members who, although not experts, have experienced a problem similar to one that is vexing me and found a way to diagnose and deal with it. On occasion I'd like to believe that I have also been of help to others for similar reasons.
Ultimately, one doesn't have to an expert to be able to provide helpful information. In that regard I have to agree with Ausieman - while he claims no particular expertise, nobody is as helpful in finding and posting
useful links and pertinent information and commentary than Gord. More than a mere expert, he has been a virtual welcoming committee and resource center for all of us. Who needs experts when you have Gord!
