I haven’t heard anything either. They are probably slammed. 🤷🏻♂️
You can still subscribe to and post to their communities from here. You don’t actually need a user on beehaw.org
Open the hamburger menu, then click the search icon and put !gaming@beehaw.org in the search box and click search. You’ll then be able to look at that community from lemmy.ml, and in the sidebar you can subscribe. You can also up and downvote, comment, etc.
Replace gaming with whatever community you are trying to join. Also beehaw.org is just an example. You can “join” any instance that isn’t currently blocked by lemmy.ml AFAIK.
