FORUMS - certain facts and questions with respect to everyone

Respected people here,

I am fully aware that there is an old age contoversy as regards phpbb; vbulletin; sm forum; IPB;

I dont want to raise any controversy but just want answers to few questions:

# OUT of Phpbb; vbulletin; simple machines and invision power board:

Q1. Which is open source (meaning whose source code is freely available).....?

Q2. Which requires paying money but with source code...?

Q2. What language and database each one of them use....?

I would really really appreciate if someone can reply to all my three questions with respect to all four forums that i have said above....!

Thanks in advance

Best regards,

sunando

1) phpBB is the only truly open source forum in your list (it is GPL licensed). Simple Machines is free to download but comes with a restrictive license which forbids source code changes. IPB and vBulletin are both commercial packages.

2) All have source code available as they use PHP which is not pre-compiled. IPB and vBulletin require payment (neither are very expensive).

3) PHP and usually a choice of several databases. All can use MySQL (the usual standard).

I think SMF allows modification of codes provided that you will not remove the copyright notices.
