F-Droid has a feature to show a user title next to a user's name. For example, see this post with the user title "co-founder".
It would be cool if we could have such titles for F-Droid developers and other contributors, and maybe even for developers of apps that are on F-Droid. That way, people can easily see who they're talking to.
Apparently the titles can only be given by admins, so there would be some manual work necessary.
Edit: It would probably be possible to automate this to some degree, eg giving a "F-Droid Developer" title to anyone with a commit in the fdroidclient/fdroidserver repos.
