does anyone know why this event date is not underlined on the calander on the left of screen?

It is on the calendar!

Topic Eastham Ferry Fun Day, 14th &15th August, 12 - 6 (by BMW Joe)
is on the calendar mate!

Never noticed that calendar feature!

I didn't notice it either, I feel a bit of a dope!

When you start a thread off, there is a button at the bottom that lets you tag it to the calendar.
