No, the cursor is at the top because that is where you start
typing. This is explicit in the default setting, which you want
anyone replying on this list to change to "start typing at the
bottom".
So this IS weird because this is a forum for Evolution, but you don't want the members to use the default setting. Maybe weird is not the right adjective. How about uncanny?
I would finish with a smiley, but I already know you'll don't
like that.
Your cursor is at the top so you can remove irrelevant parts from your full quote before you reply at the bottom. I would not call it "weird" but a courtesy to your readers who usually don't start reading your message at the bottom to get its context.
