[Mailman-Users] Toggle plain text setting for new users

[Johannes Rohr]

Dear all,

I would like to toggle a default setting for new users, name the
HTML/plain text switch. In our use case, having everything converted to
plain text by default is not very practical.

I am not sure how I achieve this, this question isn't mentioned in the
FAQ either. I am looking for a global switch to be put in mm_cfg.py or a
local config option for each of the lists. So far I haven't found either.

Would greatly appreciate any hint!!!
