Thank you for this idea which was new to me.

I guess we won't stay with mailman forever (AFAIK this is a mailman-only
feature) and we should also consider: Do we really need this? Knowing
me, i would probably always forget to set the topic "advanced" and
besides, "advanced" is a fuzzy distinction. For me, "advanced" is always
everything i don't know yet, and as soon as i know it, it's "banal".

Alles Gute
