Voice actor appearances

[Iroai]

I've always found one of the best aspects of any convention to be the special guest appearances, and more often than not, who's appearing at a con plays the deciding factor on my choice to go or not. I've got my list of voice actors that I would love to have an opportunity to meet, but given my location in the remoteness of western Canada, there aren't many conventions around that attract high profile guests (aside from the one in Calgary).

So, I was wondering if there was anywhere on the wonderful internet that lists a large number of conventions/guest lists? I would absolutely love for an opportunity to meet Monica Rial or Luci Christian or (very lengthy list, but you get the gist).
