Replacing the discussion system

Thanks for doing this!

A question about the last step: I managed to add {{HadLiquidThreads}} to my user talk page by putting action=edit in the URL, but I couldn't find any other "Edit" button. Have I missed it, or is there really no other way?

There is small [Edit↑] which is hard to see. Also it does something funny with redirects, so I had add action=edit as well.

If the page doesn't exist, it's instead red [Add header].
