Robi have generously supplied a copy of his files and they are in the publication workflow for the website. If his logo isn't the official one, it soon will be <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />
I dont know who originally designed the logo, but perhaps we can get an answer to that? It would be very good to give credits to the designer(s) on the same page where the logos can be downloaded. Phill, was you involved in that?
