So what you're telling me is it's easier to do everything from scratch? Easier than starting with hardened, updated & feature-enhanced version of current software, you say?
And though this forum has the functionality and looks of an off-the-shelf '09 SMF, theymos completely recoded the back end in hand-optimized assembler, counting clock cycles as he went along, and this '09 SMF is a sleeper with chained death under the hood, correct?
Look, I wanna believe you, but I don't. Because you'd be lying. Find it pretty insulting that you expect me to buy this "Theymos did important, complicated and dangerous stuffs you won't understand because scientific and dangerous, so don't ask!" shit.
Intrigued, do tell me more.
Theymos has made many modifications to the forum software, primarily to patch security issues. I don't know the extent of the changes, but you can search around for them in this forum as they have been mentioned in many posts by Theymos in the past. These changes may not be compatible with the latest software. Introducing these mods to the updated software could introduce new security holes yet those changes may be desired for this forum. To add those changes and then hunt down any potential security bugs is probably not worth the effort.
Good thing there's no chance of that happening with new software coded by (at best) an unknown company with no experience in coding forum software & beta tested by a handful of toadying yes-men
