The current format keeps it tidy, I think. Bigun, like some others, here, is fond of his lists (which is the only reason I post in rare and odd workings, though I know that some enthusiasts keep an eye open there for photo ops). Some discussions are going to go round and round in circles, regardless of the format and some people will always be annoyed with the mere allusion to certain topics. I cba with the fantasy bus allocations or service suggestions, on the whole, for example, do appreciate them having a set topic. The current monthly format for operator based discussion and annual format for order predictions makes it simpler to go back and find out, for example, what was being said about the Castles Express, around the time of its launch.
