https://www.fossify.org/ only lists reddit and Telegram of all services. You may be able to get in touch with some of the contributors via GitHub. And you could see if some of them recycle their user names on Mastodon.

Could you help me reach their contributors via GitHub ??

They have a contact e-mail address at hello [at] fossify.org.

Email is the og federated internet social interaction.

I don't have a GitHub account. You're gonna have you sign up for one yourself. The links to their accounts are on the website I linked to above. Just click on the avatars.

Thanks for your guidance. Followed your instructions. Got satisfactory results 👍👍

You would create an account at https://github.com

And then go to a specific app's repo and message a developer from there.

But if you just want to say hello or thank you, that hello@fossify.org email address is probably better.

Naveen's apps are great, aren't they?

You know the developer ??

🙂 Not personally, no. I just read the github site and see he is the main developer of the fossify apps.
