Can this value be safely changed in a production environment? If not, what needs to be considered if one wishes to change the value of this parameter? Is this the place to post such questions? --Dmb 06:49, 7 August 2007 (UTC)
 * Should be safe. Jlerner 16:13, 8 January 2009 (UTC)

It would be helpful to know, if this value can contain spaces (and other characters)?
 * It can contain spaces, no problem. Jlerner 16:13, 8 January 2009 (UTC)

If I change the Sitename, how can i transfer the content to the "new" "default" namespace?
