Why 3 include directories?
The ‘includes’ directory is the normal include directory, the files in the ‘g_includes’ include directory can be reused for all your fanlistings. This doesn’t matter if you only have one or two fanlists, but when you’re a collective owner, this can save you quite some space, because you use the same files over and over again. Read here how. Since version 3.0.0. there is a third include directory: ‘web_includes’. This works almost the same way as the ‘g_includes’ directory, only that it’s for the admin only and that you need to specify a relative URL instead of a path.
