[UK-CONTEST] RSGB 21/28 contest - WAB?

[Darren Collins (G0TSM)]

I've been browsing through the results of the 2011 RSGB 21/28 contest. 
One of the soapbox comments mentions sending WAB as opposed to district 
codes (Which was changed from county codes). This got my interest as I 
was asked for my WAB square a few times in the IOTA contest. So why do 
we send an exchange which no one (I'm aware of) collects? Perhaps we 
should send our 4-digit WAB square but only the first two letters are 
the mults, this would make around 63 mults available as opposed to 124 
district codes, but may drum up more interest as there seems to be a WAB 
following.
