You can mention another member in a post by doing the following:

1. With the post or comment form open, type the username of the member(s) you wish to mention into the description box. Note: If you mention a member in the headline field it will not link to their profile or notify them.
2. A blue drop menu will open containing the matching username(s) which you can select from.
3. The username will enter into the body of the description box
4. When you publish the post the username will turn blue and be clickable and route through to that members profile page.
