An user can have more than one forked repository (of the same base repo) per account. This is an issue because it makes impossible making PRs from a second forked repository.
e.g. https://try.gitea.io/Howl/ccc - If I try to do a PR, the link will be https://try.gitea.io/Howl/aaa/compare/master...Howl:master , which will compare aaa (base repo) with bbb (first forked repo), as the link has no way to recognise that it should use ccc instead of bbb.
Yeah it doesn't make sense to allow multiple forks of the same repo
Not sure if the issue here is that there can be multiple forks, or that you can't specify which fork to compare 馃槃
Because if we disallow multiple forks in an upcoming release, that would be a breaking change. But if we fixed the "compare fork"-issue we would have better fork-support than github :trollface:
