I'm currently developing some plugins. Due to the fact that they should also be available via the wp.org plugin repo, i need to license them properly.
My decision so far is to use a modified MIT/Expat license, which is compatible to the GNU GPL license. I modified/extended the license in two places (bold quote parts). I now would like to know if
- This could conflict with the GNU GPL license.
- The grammar, vocabulary and else is correct.

I'm aware that none of you is a lawyer, so it's more about your opinion. If you got additions (of any kind), feel free to tell me.
EDIT: So far I got to the point that I
- can't write anything about "legal content" and
- the area of jurisdication says nothing about any right restrictions and therefore is ok & non conflicting with the GPL.
- About "and every other copyright notice" does not conflict, because it's no restriction. It's (in my case) mostly about css & graphics.
