I've set up a slack organization for a small team.
In the beginning we had only a single project we were working on, so we just used the #general channel for the primary communication.
Now the team has grown bigger, and we have three separate projects. So the #general channel has been renamed to #project-name. However, since it was originally #general, new users are automatically added to it and can't be removed.
We would like to keep the discussion about the original project between the people working on it. The old messages regarding the original project shouldn't be visible by default for new team members either.
Is it possible to move all the old messages to a new channel and restore #general? Or how should we manage this situation?
