As you know, I've used the GMB RD database for some a few years now, just using it and contributing to it 'because it was there', but without ever noticing (or attempting to try) the 'search facility - Doh!
Note to all computer software developers - "Think of how stupid the average person is, and realize half of them are stupider than that." (George Carlin).

Memo to myself: If all else fails, read the instructions (even if you have to look hard to locate them)!
