It would be great if one could claim more than one committer nick for one project. I've done some work on a repo as another user and ATM there's no way to assign those commits to my ohloh account.

Actually, you can do that: just go to the project, click Edit, then Aliases.

You can, though it's a little bit roundabout:

1. Go to the project page.
2. Select the "Edit" tab.
3. Select "Aliases".
4. Select "Add a New Alias".
5. Choose your alternative contributor name on the left, and your already-claimed one on the right and "Add".
