I think you may find that the Plusnet forum is very good, and is very active as well.
The Lounge board is often used for discussing issues which are not BT Service related. Bear in mind that the moderators do not always get the time to go into the detail of every post, unless its a BT retail service related issue which have been brought to their attention.
