Didn't realise an offhand comment trying to indicate that in my opinion XEN deserved a higher rating would provoke such an (over)reaction!! I can see I'll have to review my posts more carefully in future - unless you just got out of bed the wrong side.
I agree with you completely about the risks - but I'm afraid bull**** is the same if it goes too far in either a negative or a positive sense. My opinion is that the share "deserves" a higher rating - I believe you are too pessimistic in terms of the short-term outlook for XEN, but I'm not arrogant enough to call a contrary opinion bull****.
