Any works I authored are to be given attribution, to the pen name Joshua Arafelis, and may be cited but not altered without contacting me. Unless there is another prior agreement, I am entitled to 23% of the revenues of the publication a piece of work of mine is part of. 23% of free is $0.00. Other than that, they are free be reproduced and distributed unless I specifically say otherwise in my posting of that work.
Side note about kopylefts: They're kinda pointless unless they're mentioned in the publication. I haven't made my way through all the Intermittens back-issues yet, but I haven't seen any notices posted. This thread should be linked to in the table of contents or something.
