I've got to say that better publicity for a given weekend's theme would be good, and it would also be pretty cool to be able to view the entries for each of the past weekends (this may already be possible using tags on the photos I don't know - but if this is the case it might be worth sticking up a non-editable sticky post with links to the topic and photos that were submitted.)

Certainly a while back there seemed to be far more excitement about a given weekend/event's photo topic with threads discussing in the forum, but I've not noticed that recently.

So with all that said I've never contributed, but I will certainly have a go now as I do enjoy looking at other people's photos.
