What El Orans said... whenyou "subscribe" to the various forums, you can choose which one you are "identified" with.Sasquatch:Oh, there are many exceptions here and there. No big deal I was just curious. I suppose the answer to my second Q would be "yes", thanks.
If you are a "Supporting member," you can change the tag line under your screen name to whatever you choose (within the rules of the ToS of course

As for the color... I think that depends on which "Identifier" you choose as the primary one. If you are a supporting member, don't want your screen name in red and can't make it go away, you can PM NetDoc or TechAdmin to change the color for you.
