The call takes place at 7.30pm, and is open to anyone between the ages of 18-30 who has a stammer and lives in Great Britain or Ireland.
This is a new joint initiative between the British Stammering Association, Scottish Stammering Network and the Irish Stammering Association.
If you do join, and it is free then you get your own senior social networking profile page where you can fill in details about yourself if you wish, along with your photos, blogs and a wall where visitors can comment.
Buzz50 is a great place for seniors to make friends with other over 50s from around the world.
It can also be performed using webcams, voice chat systems like Skype, or online games and/or virtual worlds like Second Life.
