It's rather pathetic, but the only signs of life as of late has been Vince Pfeiffer getting Amiga.org's Cafepress store shut down last week without warning for "trademark violations". This in direct violation of their own licensing agreement which called for 30% of the sales price which I was willing to add into the price if you guys wanted to pay for it. This, even in violation of my own written permission from Gateway's Amiga (which supercedes their own rights) to use said logo.
Who is Vince/what is his job at Amiga? Was your agreement with the Washington company, or the Delaware one?
Why did you (have to) enter into an agreement in the first place? There are no registered trademarks for those signs you use on your t-shirts, AFAIK.
