Thanks for your prompt response.
I attempted opening a feature request at the bug tracker of the discussion plugin as you suggested. I had to register with Flyspray to be able to set up the feature request.
Once the request had been submitted (#1394), I got an almost instant response from Andi:
I believe this may be, although I'm not certain, your website? Anyway, to allow me to pose the feature request a third time at this URL I need to register yet again at Flyspray. This all seems to be getting too incestuous for me. Help, please !!
