Thanks Trevor, that idea came out of something Mike said about keeping the traditional Lotus yellow and green, so I thought an outline logo wouldn't get us into trouble with any copyright lawyers out there and yet still retain that Lotus feel. The snag is that it's hard to get a contrasting text for the forum address, what works on Yellow doesn't always work on Green. Cheating and using the "colour circle" thing I came up with magenta which does contrast but the reaction from my tester (SWMBO) was "ugghhh, no..... never in a million years"
A banner text works ok in a single colour but I think if we go for a round one then it needs a bit of colour to lift it, even if it's only 2 or 3 contrasts.
