Board Game Arena

I set up a Group for members on my normal boardgame club wince we starting playing online due to the pandemic. For the most part this has been really useful as we can restrict game access to club members when we're playing together. However, at least one member of the group didn't notice the invite I sent way back at the start of all this. He didn't join many of our "virtual meetups" but has been playing regularly on BGA with others. He's now started coming along when we play, but can't join our games as he's not a member of the Group. We can invite him manually as a friend, but it's not ideal. I've tried sending him the invite again, but the site won't let me as he has already been invited.

How can I re-send the invite, or how can he find the invite that was sent to him months ago?

The invite is still active. You can send him the link to the group. When he visits that page, he can join
