Hugo, I strongly recommend you take a look at:

From Usenet to Cowebs by Leug and err somebody else!

http://www.amazon.co.uk/exec/obidos/ASIN/1852335327/ref=sr_aps_books_1_1/202-3848422-9668608

and:

http://www.amazon.co.uk/exec/obidos/ASIN/0415191408/qid=1086794520/sr=1-2/ref=sr_1_2_2/202-3848422-9668608

There are several other interesting ones, but I think you could easily write a book like this yourself... actually, perhaps that is something you and Simon could look into? I've looked at one or two online community design books and they were not very good.
