If I revert a large amount of commits in sourcetree, will it affect others?

[Tesa Wilson]

There is a project that I had worked on, and I want to reset my branch back to a much earlier commit. But, will it affect other peoples commits or backtrack the entire site for everyone?

To begin with, resetting your branch won't have any effect on others until you Push, and only if it has been pushed since it got past the commit you are resetting it to.

If/when you Push the branch, it will cause some problems for anyone who has checked it out. It will only backtrack whatever "site" you are talking about if it pulls and checks out the branch you are resetting.

Resetting won't modify any commits, but some may become inaccessible via the GUI depending on whether they are part of any other branches.
