Mobileme Publishing is not working for me

Problem: TrailRunner asks your keychain for a Mobileme authentication. The keychain itself uses your Mobileme system preferences information. If your keychain is not set up properly, TrailRunner is not able to access your .Mac account. This might be due to a problem with your keychain.
Solution: Read the following support article on how to fix any keychain problems:

Problem: You published your weblog to Mobileme, but the changes are not visible.
Solution: It might take a while until Apple has copied your new website content from your iDisk onto your webspace. Please wait a couple of minutes and then reload your webpage.
