Looks like it requires mods to postify.php and post.php. Can you let me know what lines of code need edited in those two files please? Love to have this.
[size=12]I realized I had no alterations made to either post.php or postify.php and uploaded this as instructions said but it's not showing in my BBCodes Admin, any ideas?[/size]
Have a look if you have within the directory locale/"your language"/bbcodes the file mention.php. Also have a look if there exists the subdirectory "mention" including some files in the directory bbcodes.
The files being overwritten are mentioned in the readme including what is modified within them
