We have both created polls that seem to work technically so next question might be do we actually want to have a go at the voting for real.
Would need some suggested posts with organisms that people want to say are their favourites and perhaps one poll per month or just have them occasionally at random times.
Also clearly I as admin do not have to set them up, anyone can do that but there does need to be a collection point for suggested observations and someone to decide on 10 of them (actually can have any number but don't want too many or they won't show up properly).
Will wait for more comments on this to see if others have completely different ideas. Perhaps not 'favourites' but some completely different question/idea, one of the main ideas is to get more people involved and perhaps those that don't normally look at the forum. The votes could be advertised elsewhere on the site.
