 605                 Your site name should be a relatively short word. It'll appear as the namespace
 606                 name for 'meta' pages as well as throughout the user interface. Good site names
 607                 are things like "<a href="http://www.wikipedia.org/">Wikipedia</a>" and
 608                 "<a href="http://openfacts.berlios.de/">OpenFacts</a>"; avoid punctuation,
 609                 which may cause problems.
