Hi All: Unfortunately I've not experienced the same satisfaction with forums that I've received from the PBS listserve. I think the problem revolved around the fact I had to login to yet another application to see what had been posted - over time it simply became too cumbersome (sad but true). Yahoo, Google, etc. obtain revenue from advertisers based upon the number of subscribers they have. If one of these businesses is blocking legitimate traffic and is unresponsive to requests to solve the problem I suggest applying economic pressure and moving to a better ISP. In a polite way I would let them know why they lost your business. Plants are not the only organisms with latin epithets that will hit these super sensitive spam blockers. Based upon the threads (apologies to anyone miffed with my changing the Subject line but it seemed appropriate) the problem is not with PBS but rather with the Internet Service Providers that some members use. I suggest focusing on fixing the part that is broken.
