implement this. I have thought about doing this for a long time, it just slipped off the radar when we were adding all the other enhancements.
I've often suggested keeping the subject line blank, forcing the poster to create a topic, instead of the default behavour:
re: prior subject title.
The logic is that the subject line can tell a prospective reader whether or not to read the post. If the subject line reads
Hey thanks for all your help
I am less inclined to spend time reading the post. If the subject line reads
I am more inlcined to read, despite the fact that the two posts (in this example) might be the same.
I know this is not a major point worth worrying about, but I feel that all readers would be better served if they had a better clue whether or not to read a post.
