Fran, I think we could do with an area specifically for Good Luck Threads (like the for sale, off topic, honeymoon that kind of thing). Say if there were 30 brides for September that's 30 new posts on the first page of wedding planning which means to find previous posts your have to trawl through page 2 then page 3 etc. I know there is the my discussion box on the right hand side, but sometimes that's not even used (well I don't use it all the time).
Technically a good luck thread isn't wedding planning as such - although it kind of is still wedding related.
I just think it would make it a bit easier to find your good luck thread, the wedding planning bit will not look so jumbled and it keeps all the popular posts on the first page together in one sort of 'block'.
