@evgeniy-onegin like change the colors displayed in the UI? There are many NodeBB themes you can try. If you want to customize yourself you can use custom CSS in the ACP.
Converting MyBB to NodeBB in 2020?
I currently have a MyBB forum that I'd like to convert to NodeBB. I am looking for some up-to-date info on this, as all the threads I've found are from 2014.
Is it possible to convert all my users, posts, and threads over to something that would work with NodeBB? Would user logins still work or would my users need to reset their passwords?
Thanks in advance!
