Default option is to transfer rights to the Wikimedia foundation and a checkbox if it is GNU FDL-only.
I do think that we should prefer radio buttons. We don't want somebody to forget to use the checkbox. (And making the box start out checked can be confusing.) With radio buttons, if they select neither option (all rights to us, GNU FDL, CC BY-SA or whatever we might add later), then an error message with big shouting red text can come up. That avoids mistakes.
But this just came into my head, what about the times that someone copies (GNU-only) text from the WP main site but does not flag it as such.
This is just like copying proprietary material to WP and not flagging it as such (which flagging you can't do -- so it's just like copying proprietary material to WP, period). This is a copyright infringement and should be treated as such -- although instead of deleting to fix it, we can flag.
BTW, Anyone find the good link to the GNU FGL compatibility with other creative licenses yet ?
Nope! Did it ever exist?
