Why should we need to join their telegram group when we're literally asking them on their own announcement thread? Like it's supposed to be a place they respond aswell
They might be busy to manage the telegram group and couldn't give any reply to the announcement thread. Just saying my opinion.
I think the 4RT don't have a telegram group. They didn't even make it available in the thread. It is not so good to neglect something like this as it will be the way to make the community grow.
