Sorry for the lack of follow-up on this -- I've been lettering like a loon this week!
Short version: the deadline extension seems to have really made a difference to this compo, so I'm reasonably convinced that there is still some lurrve for the comps! However, it does appear that four weeks is a struggle for a lot of people.
So ... what I thought we'd do going from this compo's result is put the comp on a six-weekly schedule (with various extensions, we've never actually managed a monthly schedule anyway) and see how we go. Does that sound like a plan, peeps?
Cheers!
Jim
