Welcome to U3ACommunities

U3ACommunities is a free on-line platform for enquiring minds. It hosts a number of subject based groups who meet on-line monthly. It is independent of the Third Age Trust.

Whilst most of our members are beyond the age of retirement, we do allow anyone to join.

Use the GROUPS menu above to browse the groups and SUBSCRIBE to join one or more groups – you’ll then be emailed about new meetings and other posts. Both subscribing and attending meetings are free.

Individual groups may allow commenting on pages for any post-meeting follow-ups or discussions. The previously offered discussion forum has been disabled due to lack of use.

Why not join the fediverse u3a.social for discussions ?
