Describe your proposed improvement and the problem it solves.

see third party lua implementation here .

Bbcode is very useful, if I want to write a long forum post I can write it in markdown or ODT (that have good editors), and then convert it to bbcode and then post it.

BBCode has various variants used by different pieces of software (hubzilla , phpbb, fluxbb),i am interested in using xenforo which seems like a fairly popular system. Although I am not sure if one of the variants from the lua reference fits xenforo perfectly, I think I used the “ fluxbb” and it worked ok.

Describe alternatives you've considered.

Keep using the third party implementation, but that is not as convenient .
