No worries - glad to distribute (and now under explicit CC share-a-like licence) will keep word and PDF docs updated at that location.
All linked from with word doc (editable) available from http://www.lancs.ac.uk/staff/wrightst/
Really hope we can enable annotating (but no other editing) on other users in one-wiki-per-user asap as that would massively increase educational options and value.
