Neil, I'm going to defer responding on this to give others a chance. I do have some comments I'd like to make but it strikes me that sometimes I say too much and don't give others a chance. So my failure to respond on this should not be taken by you as disinterest (though perhaps you are not disturbed by THAT prospect!). Instead, let's see what others want to say on the matter first. -- SWM ========================================= Manage Your AMR subscription: //www.freelists.org/list/wittrsamr For all your Wittrs needs: http://ludwig.squarespace.com/wittrslinks/
