Dear Marty,
it is indeed not obvious yet to me whether your module will be helpful or not. As you said one of the problems would be to compute the total. Another problem is that we do not currently allow our members to register on our site. This would of couse help a lot because it would make it clear whom one trusts. I didn't even think about that so I'm grateful to you for having pointed that out. Thanks for having mentionned the module ! It's always good to know what exists !
Best wishes, Sherab.
PS: assuming we'd allow registered users to update the counter, how should we do to allow them to do just that and nothing else ? One solution I see would be to create a special content type and to enable editing for just that content type for the registered users, but creating a content type just to have the right permissions seems a bit clumsy to me.
Best wishes, Sherab.
