Is it ok to add full tutorials to wiki.okfn.org? Or would that be better on a standalone site. Wiki software is good because it allows multiple contributors & editors.
For example an [OpenSci wiki project][1] on Github contains a guide that could be contributed about working with open data in Google Fusion Tables and Spreadsheets.
