First of all, the thread starter kerthivasan is not at all wrong. Yes, It is possible to ship the entire forum content on a DVD but that would require special programming scripts.
And it would not take 100 GB or 250 GB, may be less than 1 GB will be enough.
Just a question to all those who said what not things to
kerthivasan, how much do you really know about PHP-MySQL programming huh? What is the level of your skills?
FYI, it is possible to write such a script.
