thanks for the link and replies.
here i found a reason for the non-existing description:
meanwhile, since naming has some limits, it’s better be short and also for tags it’s better not be several words (or it needs a _ to join the words); description would be useful.
a sample in our forum: we have the “energy” tag used for topics which are about energy usage or energy waste. then topics about positive psychology (e.g. “i got lots of energy doing bla bla”) are tagged with the same tag as well!
and such things create extra moderation effort.
