In the vU3A, the activities take place on a variety interest pages in our wiki website.
There is no need to formally join any vU3A activity, you just visit, read and make contributions.
There is usually much information to read which can be a great help for those venturing into new subject matter areas. Dropping in every now and again is the norm.
There is the ever-popular Coffee Shop which is an agreeable place to visit and have a chat in the form of written comments in the Comments section of the page. The nice thing is you don't all have to be online at the same time to have your chat - particularly when there might be contributions from around the world, for example, Australia, as time zones are not a factor.
