Thank you liraz, I followed your advice and installed MediaWiki through the Virtual Machine solution. I am sorry I can´t give you any feedback on the other proposed solution (running the scripts to use the USB thumbdrive in live mode). Now I have one followup question, but I don´t know if it belongs here or on the MediaWiki forums: now that the wiki is up and running within the virtual machine (i use VirtualBox), how do i access it? The IP address that MediaWiki provides on startup is the one of the hosting machine, and I don´t seem to be able to access it. Any help?
