Wikis are associated with a repository on Bitbucket and it is very unlikely that we're going to associate a wiki directly with a team instead of with a repository. You can have a repository that everyone on the team has access to that has a wiki.
I hope you guys would reconsider this. This would help us a lot in staying organized. The workaround you proposed wont work if you tend to tie tickets to wiki articles and vice versa. We have a team project with multiple repositories: one for iOS, one for Android and one for Web. Each repository needs its own set of tickets and code, even its own wiki but for overall overview of the platform, the general architecture, database structure, APIs, etc... that documentation has to be shared across the projects.
If we create a general repo that everyone has access to, we would be able to use the special markups that we all love such as:
I agree with this completely. The overview page of a team shouldn't be a listing of the teams repositories but of a team created wiki page. This would help my teams stay organized as well from a top level perspective.
