After moving in to our new server last month, our next large project is to set up some new Fediverse platforms. One of the most requested of those was Pixelfed, which is an image sharing platform.
You should be able to sign up here: pixelfed.ca
As with any new instance, some issues are to be expected and while we’ve done some testing already, please bear with us as things get going. For any support related issues with pixelfed.ca, please post in the new !pixelfed@lemmy.ca community
Unfortunately you can’t do that yet. That’s one of those things that will hopefully be possible eventually with the Fediverse. Right now you can view content from elsewhere, but the accounts are tied to the instance that you are on.
It is possible to sign in with a Mastodon account on some instances, thanks to an integration they set up. It might be possible to do something similar with Lemmy, but I imagine it would be more difficult. Mastodon and Pixelfed were relatively similar already.
For example, it’s technically possible to view your lemmy user on pixelfed.ca: https://pixelfed.ca/i/web/profile/798599852495369073
You can also view a pixelfed.ca user on here: https://lemmy.ca/u/shadow@pixelfed.ca
However both profiles are blank, so federation between Pixelfed and Lemmy isn’t as smooth as say, Pixelfed and Mastodon
