One of the reasons Joyce and David from BCN have worked so hard to keep the BCN Forum software is to keep all the old posts still available and easy to search. There is such a wealth of information there!
I use this option a lot.
I actually even use it to sometimes search my own old posts. So even though you are always free to ask questions, it is also good to have a look by searching. You'll usually find something on any bead that is out there.....
