I have set up a wiki to help me get my head around how it works:
I wasn't finding it very easy to navigate around and was getting quite frustrated with it. But now I have spent some time putting in entries, editing it and engaging with other people's editing, I am starting to get the hang of it. It has great potential for collaboration, especially if you are working on a project such as developing guidelines or writing a multi-author paper. But you will need to spend some time getting to know the program's layout and functions.
Please feel free to have a look at the wiki and make changes to it or add material. The premise is we're developing an information leaflet to give to pregnant women about the pros and cons of eating cake in pregnancy, in order for her to make an informed choice about whether she is going to or not.
