Frequently Asked Questions

I can't seem to join the session on Butter, what's up?

Butter best supports a desktop browser – and downloadable desktop app.

Check these firewall instructions to ensure you can access the tool. Let us know if you can't get access and we'll explore alternative tooling for future sessions.


Do I have to engage during the session? I'd prefer to just listen.

We appreciate for some that another group video call is just all too much, particularly if your learning style prefers asynchronous learning – and learning by oneself.

If you're open to it, we encourage a level of engagement that will involve taking notes and sharing thoughts vocally about those notes. 

If this type of interactive session isn't for you please do let us know and we can explore alternative options. This is an inclusive community and we look to improve the inclusivity and accessibility of all our events.
