:Hi Jim — nice to hear from you!  Thanks for the interest and advice.  Re SOC models, I think a section on "Examples of SOC dynamics" would be good, with links to subpages on, say, BTW sandpile, forest-fire models, Bak-Sneppen, Olami-Feder-Christensen and maybe one or two others.  I'd also like to do a page on the Oslo ricepile experiment. 

 :On power laws, I'll be meeting up with a few scientific colleagues in the latter half of November and I'll have a good chat with them about how to revise that article.  Ditto self-organization. 

 :Alas in general I'm not going to do much writing in the next couple of weeks because I have a thesis to get finished...  But I'll try to drop in some words when I can. ;-) 

 :All the best, — Joe aka
