 Matt's blurb: Because I release all my contributions (including photographs and diagrams) into the public domain, there is no legal requirement to fulfil any special obligations when reusing them. Having said that, I would appreciate attribution &mdash; that is, if it's reasonably easy for you to do so, to list me in the credits somewhere or to provide a link to Wikipedia. And feel free to drop me a note to let me know if you find them useful &mdash; I'd be chuffed. If (and this I suspect would be quite unlikely) you make some huge profit from a use of the work, you might consider passing on to me some appropriate fraction of your profit. Again, to emphasise, none of the above are legal obligations, only a casual ethical prompting. One analogy is that of a busker/street performer; if you enjoyed such a performance, it is appropriate to express appreciation for this &mdash; by applause or a donation for example &mdash; but it is certainly not obligatory. And above all, I'd prefer to see my contributions reused than not, so do not let any of the above hinder your reuse!
