This is, by far, my favourite site. The reasons have been said: knowledgeable and respectful people always willing to help, simple site to use, white background and no clutter, well managed, and full of useful information for us genealogy types to keep us endlessly busy. I see little reason to change it, but will add my two-cents worth.

My one bug-bear is not being able to see the message I'm answering while composing a reply. That's been mentioned already so I'll add my vote for that.

I also like to see more informative heading lines but unfortunately these are authored by the message-writers who need education. Perhaps a nicely worded request at the top of the message box would help? And if the message-writer in a thread is changing the topic, they should change the header too (and I'm one of the worst for this, even though I know better).
