I've just posted this to the old group, but I thought it might be useful to paste it here too:
If anyone wants to set how their name is shown, in a group, the procedure (when logged in) is:
Click your email address, at top right - this is only shown to you, not to others, and is your actual login ID for groups.io.
Click Account, on the menu that pops up.
Click Identity, on the left.
You can now click Edit next to each group you belong to, to set the "display name". They don't all have to be the same.
There's also a display name for your account, which I assume will be used as a default - I'm not sure.
Apparently, if you don't set one, and reply to the group by email, it will show your name as it appears to others when you send an email, or failing that, the first part of your email address, before the @... You might not want that. Also, if a lot of people only show their first name, that might get confusing.
None of this was immediately obvious to me, so I thought I'd share what I've learned.
