How customizable is PHPBB2?
Will it cost ANYTHING to run, I really don't want to spend more on this site than a domain name and some space.
What do I do with PHP and MySQL, gunna need the 'Mysql and PHP for dummies' version here guys..
Completely free, as long as you agree with the lisence agreement, which is quite simple, nothing dodgy in there (i think, just gave it a quick glance just now).
As for how customizable:
You can change the look by replacing their images (for button, icons etc) with your own. You can edit the stylesheet (css, easy to pick up if you dont already know it) or create your own, getting all the class names/div ids that are used from their existing stylesheet.
You can obviously make the layout of the forums/categories or whatever, make your own groups for members, change access rights for different sections of the forum (the usual basically).
You can probably do more detailed things, i havent used it a lot, but no doubt you can change most things except for the structure of how it works (unless you want to edit a lot of the php yourself).
Now, setting it up is reasonably simple. You just need to install MySQL on your server, create a new database for the forum. Install php on your server.
Download phpBB2 and move it to the directory you want it to be found in on your site (eg: www.mydomain.com/phpBB2, name the outmost folder whatever you want, defaults to phpBB-2.0.22).
The instructions to install are all included. If you testing on your own computer, open your web browser to
http://localhost/sitedirectory/phpBB2direc...all/install.phpthis will give you a form that you fill in with details of your database name and password, then admin details for the forum.
And thats basically it, if you developing/testing it on your own computer and havent already got a server (IIS/Apache or whatever), MySQL and PHP setup then i can (or someone else with more knowledge) take you through how to get those running, but you dont actually need to learn any, its all done for you.
Theres probably a few things you should do that are mentioned in the phpBB2 install guide to secure you forum, changing access rights on the server of specific files and things like that, but im not an expert on that, i think most of its contained in the install guide.
EDIT: completely beaten by Nikas, ah well, must type faster next time
