I'm slammed today; can't really spend any time on this. Can somebody do a little digging and see if we can find the organizers? They need to know that Rick's reputation will keep a lot of pros and fans away, even if he doesn't try to rip anyone off.
According to what I'm told, Rick does a lot of volunteering for veterans' groups in his area and "has raised a ton of money for them." (And Hitler painted roses. We all have our good points.) As genuine as his interest may be (giving a huge benefit of the doubt) his reputation in comics circles will damage the convention's prospects. And there is nobody to blame for that but Rick. It's not libel if it's true.
