Moved your new page
Sorry about that - the old URL is still active; if you go to the old URL, you will be automatically redirect to the new one, which is formally here: http://wiki.ubc.ca/Sandbox:CTLT_Institute_Accessibility.
Another way to find pages that you have been working on is to use the "My contributions" link under the Personal Tools heading on the lower part of the left hand navigation column.
Again, my apologies for disrupting your workflow. Please let me know if I can do anything else.
