There are a few ways to get in touch with the ivatar/libravatar developers:
If you have an IRC client already, you can join #libravatar on chat.freenode.net.
Otherwise, you can use this simple web interface
Please keep in mind that you may live in a different timezone than most of the developers. So if you do not get a response, it's not because we're ignoring you, it's probably because we're sleeping :)
If you have a question about a particular bug, or some feedback on it, the best thing to do is to comment on that bug itself.
We use the bugtracker included in our GitLab instance
If you've got a proposal to discuss or prefer to write to us, you can join our developers mailing list
Identica / Twitter
You can also put short notices to our attention on Identica
Our Mastodon profile is available on https://photog.social/@libravatar
