Author thereof. Wasn't expecting it to be posted over here though...at least not until I decided to do it.
It's not exactly a finished project but the 1.5 release is compressed, packaged, and ready for download I guess.
I lol'd because it's true. ;__;
I originally wanted to code somewhat of a PHP counterpart to kareha, with a few features added and a few features removed, but after a while I just wanted to code an imageboard/BBS script that worked and ran efficiently/securely, despite the fact that it indeed was coded in PHP. It orignally ran comments through a MySQL database but after realizing the database structure for the boards sucked ass I just switched to log files.
I'm going to be releasing modifications to the script that can be implemented by users if they want, instead of shoving it down their throats like another popular hybrid script (>>80 Hi Trevor!), like a catalog mode, album mode, subback for imageboards, etc. There are some features I'm 50/50 about, like adding the ability to edit posts, hide threads etc. I mean, they seem like somewhat decent features, but I don't want to end up masturbating with javascript.
Only thing I'll ask you about is if your PHP 2ch textboard was by any chance based heavily off of the freestyle BBS script (from the creators of gazouBBS).
