Submit lists to freedb

Hi,
I love freedb from MP3TAG! - 99% of the time it gives good tagging info for CDs. However, recently I have bought 3-4 CD compliations (BBC Radio 1 Live Lounge) that don't appear accurately in freedb, and I want to update their information online from my own manually entered tags, so others can benefit from my work.
On the freedb website it says you can do this from MP3TAG but I can't figure out how.
Any help / ideas?

Please point to the place where the freedb website say, that Mp3tag can upload or edit informations into the freedb database?
