I'm missing in the list of contributors

[mreiche]

I was showing my coworkers, that I used to work on a public Open Source project, but unfortunately I'm completely missing in the lost of contributors (https://github.com/telekom/testerra/graphs/contributors).

Is there any reason for that?

Did you remove the associated mail address used for the commits in your profile settings?
Thats may a reason, because when searching for a commit of you, your profile name is not linked anymore.

Yes, the changed email address causes the deleted history.
Well, there are possibilities to fix the email address with filter-branch but this is very tricky because the whole Git history will be written again.

At the moment I didn't find a good solution.
