A bunch of big updates for Basecamp 3
Jason Fried

We’d previously created a Basecamp for each team and it did clash a little so the concept in this update of splitting Teams out is a good one that works well for us.

I would highlight however that you can convert an existing basecamp/project into a Team within its Settings.

Easily convert a basecamp/project into a Team

I didn’t realise this until I was halfway through moving everything from the old basecamp into the new Team I created!

Happily we’ve only recently returned to BC (previous BC2 user) so that was relatively easily reversed.
