Thread:Project:Support desk/GNU GPL/reply

Hi!

1. Yes, you can. Just edit skins/Vector.php, or maybe better MediaWiki:Common.css or create an own skin.

2. I am unsure about that. Consult the text of the GPL to get tht information!

3. You got a "work" with the MediaWiki package, e.g. the source code itself, the CSS design and so on. If you change them (which you are allowed to do) in such a way, that you afterwards have a "derivative work", then this work must be licensed under the GPL as well. E.g. if you slightly modify the skin, then you must licence this skin itself under the GPL. If however, you create an own, new skin, then this skin is not derived, but is your work and you can licence it differently. All this does not apply to the actual content in your wiki. You can licence your own content in the way you like; there are several variables, which you can set to do that. See Manual:LocalSettings.php.
