There was a big debate a while back about what colors to offer, mainly from the accessibility point of view - in other words, what people preferred for easy viewing under different circumstances than the latest big bright screen and perfect 20/20 vision.
I'm afraid all I took away from that was that no one could agree at all. I asked for examples of good forums or sites but none were forthcoming, so apparently there are no forums out there that people find easy on the eye for all purposes. If we get some suggestions with examples, and there is general agreement, then we'll do something about it. Otherwise, whatever we offer will appeal to one person and annoy lots more, so there is little incentive at the moment.
The logo: it will get used more as we move along. For example there will be a business card option with the logo. The first run of the contest-winning biz card design is under way, when that has been out there a while we'll do card #2 with the logo. Also it will feature in our new Reference Section that should come online in the next couple of weeks. T-shirts are another thing in the pipeline.
The cards will be given out free by the way, most likely in blocks of 100 on receipt of an SAE, stamped addressed envelope. Not long now.
