- FiXato (scripter, blogger)
- FlashCode (weechat creator)
- Nei (awesome scripter)
- nils_2 (very original scripts)
I asked each of them to type :
/script list -o
to have the list of their currently loaded scripts.
I counted and the winner is buffer_autoset.py with a perfect score. Among scripters (FlashCode, Nei, FiXato, nils_2) the winner is also buffer_autoset.py with of course a perfect score.
