A wiki is just a simple form of web site which can be edited quickly and easily by a number of contributors.
Why not have a go at adding an entry for your school? The East Lothian page is looking a bit empty just now.
The feedback so far is that people are finding the wikis really easy to use, and teachers are starting to explore various classroom uses, including as e-portfolios.
We’re currently getting permissions sorted so that all East Lothian Glow users can create their own wikis; if you can’t wait please get in touch and we’ll prioritise your account.
