@ Surfi test some known sercuity bugs and see what a potential hacker could do to these forums. Remember this is one of the most popular mybb forums around making it likely to hacks.
Plus the mods are already done and the basic code is wrote. It just needs to be changed to work with the new mybb files. Which some mods maybe hard however the lasest posts one it a new page and should be easy to update.
Plus mods maybe even improved when the update occurs. However we totally understand if updating the forums can take months and probably the whole process will start next month, as this is a busy season
