Create it
- Sign in at app.rosterr.work.
- Choose to create a workspace. Rosterr lists the Roblox groups you own.
- Pick your group.
The workspace's address is your group's ID, so it always matches the group.
The free trial
Straight after, you can start a 30-day free trial of Pro. No card is needed to start, and each workspace gets one trial. You can also start it later from Admin centre > Plan & billing.
The checklist
Your Overview page now shows a getting-started checklist. It ticks steps off as you do them, and this course follows the same order, so you can use either to keep track.
