Julian and I were just IMing about how to set up a new Subversion repository - and we both commented about how this process should be documented. King set one up last week, and we said the same thing then.
So, I bit the bullet, and wrote up a first draft of the documentation for the process of creating a new Subversion repository for a Learning Commons project.
I left a page to list all documentation for the Learning Commons, in case the idea takes off and others start doing it...
I've used wikis to store "spontaneous documentation" before - but I'm hoping to keep the wiki as part of the formal documentation process. We're about to head into another Learning Commons website rethink, so it might make sense.
