You could start by alphabetically ordering the Sidebar! On a serious note, I think Wiki's are a fantastic way of accumulating knowledge (Wikipedia being the perfect example) regardless of censorship and sabotage concerns. Whilst they are open to abuse, as long as we have a system capable of making people accountable for their edits (I.E the 'Recent Wiki Activity' section) they're an incredibly useful addition to social networking and amassing information.

I added them in the order that people registered but I think you are right, consider it done!

Paul,
I'm glad to see that you have identified a role for Librarians in the Social Newtworking milieu, even if it is to put lists in alphabetical order! This is a route that I may go down in the future in terms of providing Library support to students, e.g. help with sources of information, reflection on information literacy strategies so all comments are welcome and will help me to formulate my future stratgey.

Paul, how do I change my avatar?

Janet your skills as a librarian could definitely help with research students, making suggestions on titles or simply helping them to find literature relevant to their interests. I haven't heard of of a similar occupation before, but it sounds like you have a good niche for exploration.
