Hi all,
The facebook ID entry field in our profiles is very confusing indeed. The actual Facebook ID number is not obvious, so most people don't understand what they're supposed to enter in there. I myself put my Facebook profile name in it the first time, because I didn't know what else the ID could be, and then I found that my facebook button didn't work.
Eventually I found out how to find my Facebook profile ID number so I entered that in there and now it's all working. But I have since tried clicking on other peoples' facebook buttons and they fail in the same way that mine originally did, so I don't think I'm the only one that's confused about what to enter into this field.
AH.
