In late 2008 the machine hosting the ALU wiki disappeared from the internet, taking the content of the wiki with it.
We were able to recover the content from various sources and import them into a new wiki. This was an automated process, so some pages might have lost their content or formatting. In some cases the content might exist in a previous version.
The import scripts were not perfect, so if you notice something obviously missing, email drewc at tech.coop and i'll see if i can sort it out.
