Mixing it in the wiki

Have just finished the wiki section of CCL Learn, and should be feeling totally comfortable with contributing to wikis now.....ummm...not so much. I think it is a case of performance anxiety - what if I do something wrong, what if everyone laughs, why would anyone be interested in what I have to say (although as my friends will tell you, that has never stopped me before).

I guess it is just a case of taking that first step, grabbing the bull by the horns, crossing that bridge, getting out there and mixing those metaphors.
