I have a problem with some PHP bugs when people put in special characters in boxes and save it e.g. when they change there username or send a message to each other, if they use special characters or even try typing in php code it lets them and causes errors etc.
We need this fixing in 3 places, registration page so when they join they cant use special charcatgers, message system, forum and username change setting.

I can validate user's input and, say, remove special characters. Or I can show message "Invalid chars" and allow user to edit his input. I need FTP access to start right now.
