I know some of you are keen on features that are similar to Facebook but the tag feature will be really handy. Say there is a post about something poo coloured, you could then think RR would like this I'll tag him! Then you'd type @ then the username (no space between the @ and username). If the username is long a suggestion box will appear in the bottom left for you to choose from. Have a look at this rickyrooo1 !
