It's been suggested on another thread that it would be a nice idea for mumsnetters to be able to start polls. i.e. when you start a thread you can set up a poll to go with it and specify a start time and end time. Then people can vote and see a page showing the vote balance.
Votes would be private and limited to one per nickname but results public.
So for every Am I being unreasonable? - type thread you could actually get a majority view if you wanted.
Anyway Tech says he can do without too much trouble - what do folks think - would you like it or no? (now if only we could start a poll on this...)
