Another forum I go to has a thread similar to this. But instead it's called (the forums name)'s black book . E.g a thread of all the members details and contact details. Quite nice to flick through if you want to add someone, or find general info out.
Introductory thread seems like it's for new people only. Perhaps a rename or some sort to suggest that it's a thread for general info on fellow forum punters.
Black book is a good start....
