Just use the current standard Forum Logo on clear for the sides of the screen, don't over complicate it, perhaps add some boobies though?
Small sticker for screen, race style with forum logo and member name in a simple Helvetica-style font would be nice. Something ideally in that "frosted" grey colour on a transparent background so that it's subtle.
We haven't got to have a special handshake have we? I've tried that before, it's over rated. What about a secret question? Could be, Do you know Ducbird?
Best looking sticker is to make it up as current logo with clear background as @Exige suggested. These can go on screen / visor (if all on one line) and look quite neat applied to a bike.
I'm happy with this Are we going to be best off starting a new thread with a simple pic of the intended design and to gather peoples names on a list then or are we just going to do it through this thread? If nobody else fancies the job of collecting names, getting them made up and distributed then I'm happy to help as previously mentioned... @Rob @El Toro
