For one thing it is the last trading day before Christmas, I think most people have already left their desks! They other thing is, by the time you've got enough people to club together and started negotiating with the holder etc, the overhang will probably have gone naturally anyway if JDM's estimate of 6 weeks is anything to go by? And of course the financial aspect - no point in offering a few £100 I wouldn't have thought?
So please don't take it personally if you don't get enough interest!
