Musicbrainz is now testing a host of new features including the ability to create a list of all your releases on the Musicbrainz server. This is a really good time to add your two penneth because server releases don't happen that often.
In jaikoz 2.6.0 I added the ability to upload your collection to Musicbrainz, so now Musicbrainz have made this available on their Test server you can try it out.
This is what you need to do in Jaikoz
On 'Musicbrainz/Match tab' change the value of Musicbrainz Server to http://test.musicbrainz.org
On 'Musicbrainz/Submissions to Musicbrainz tab' change the value of your password to mb
Select Action/Remote Correct/Submit Collections to Musicbrainz to submit all releases with a Musicbrainz release Id to Musicbrainz.
Then to see your results in Musicbrainz login to http://test.musicbrainz.org and click on My collection
More details about this feature at http://wiki.musicbrainz.org/MusicCollectionIntroduction
There are a couple of bugettes at the moment. Jaikoz might display error 400 when submitting releases to Musicbrainz if any of the releases are not in the test server
but the other releases are still submitted successfully, go to the website to check.
If you have a problem with your login on the test server you need to remember to use the password mb not your usual password and you remove any cookies for test.musicbrainz.org and musicbrainz.org
