It's been a few years - good years - since I last used WebEx. There seems to be widespread opinion that WebEx gets worse with every new release, and after trying to use it today, I agree.
Fidelity wants me to join a "Webinar" (minus ten points for idiotic unnecessary portmanteau) about investment options. (Options that I really don't care about, to be honest. My portfolio is already sufficiently diversified to have survived the liquidity crunch; if something worse than that happens between now and when I quit drawing a paycheck, I doubt anything Fidelity has to offer me will help.) They sent me a Word document (because that's what you need to send someone instructions by email) with links (can't just supply the URLs) to WebEx.
One is for a list of WebEx system requirements. It returns a 404 with a simple "Not found" message. Good job, WebEx; I guess it'd be too much work to put in a redirection for that.
One is for the WebEx test/setup page, where you go to get the applet. That crashed Firefox. Awesome work there, kids.
So after returning to the WebEx Disaster Zone in IE (because if that crashes I don't care; I don't use it for anything that doesn't require it), I figured I'd see if the Firefox problem was a known issue. Click the "Technical Support" link ... and get a 404, this one with a handy quotation from RFC 2068 10.4.5. 2068 was obsoleted by 2616 in 1999. And, of course, the intersection of people who a) would find a quotation from the RFC useful and b) don't already know where to find it and c) don't already understand an HTTP 404 error is likely the empty set. So WebEx wins the "idiotic and thirteen years out of date" award for this one.
One more try. Click "Contact Us" and then "Technical Support". Oh look - it's our friend Section 10.4.5 again!
Cisco's a pretty big organization. I bet they employ some technical folks who could sort this stuff out.
