I keep trying to enter a channel for the adsense rev sharing but every time, no matter what I enter I get an error: "You did not enter the correct format for the Google AdSense Channel ID field. Please read the field description for the expected format." Unfortunately there is no description of the expected format which make it hard to read. Any suggestions about what I can/should enter so it will be accepted? Also, do you really get a -1 rep if you give someone else neg rep? I think that's kind of crap to be honest. If someone else is being a butthead I shouldn't be punished for thinking he's a butthead and rating him accordingly.
The channel id is a ten digit number. You have to set up a special channel to use with your DP account. This channel id is set up in your Adsense control panel area. This keeps members from running around giving negative rep indiscriminately.
