Can't connect to other users
I am having trouble seeing other users that I know are on-line in the buddy window. Their user name is greyed out and I can't see when they go on-line.
They are in my address book and they have .mac.com accounts.
Do I have some issues with setting up sharing?
I believe this is the fix. The address book is where I have entered the contact i want to chat with, but the adderss book entry is not enough: you have to update the entry after adding it in iChat.
Once I had done that, the user is found, no problem and it works.
