Did you send them a message from that link at the bottom of the block page? I did.
I did as well. The problem is is that OpenDNS gives you no way to whitelist a URL without running their dynamic DNS proggy, which doesn't (at least as I can find) give you URL you can use in the external world to have certain programs always be able to find your box. something tells me that running 2 separate dynamic DNS updaters will not go well.
If the Earth were flat, cats would have pushed everything off of it by now.
