Hey, I found bug in your system. If i write "https://<<login>>@bitbucket.org" in text editor, and click on preview link or save button, i see something like this: "https://<<<244228680>>>@bitbucket.org"... I think number in <<<244228680>>> it's someone id number)))
And i have wish to your wiki. It's great, but users can't paste links for own wiki pages, which created... It's doesn't be comfortably...
