What is a wiki?
You're reading a wiki now. It is a repository of knowledge which can be edited by anybody—including you. The most famous wiki is, of course, Wikipedia, but there are many others. This kind of collaborative venture has proved to be amazingly successful, not least because it allows us all to add a bit of knowledge to the common good.
Why use a wiki? A wiki has an advantage over a newsgroup or a forum—the wiki is continually improved and updated. In contrast, a forum may briefly excite a huge amount of passionate interest with the consequence that it will wander to untenable length and finally be unusable.
I've got a question. You're welcome to raise Teflpedia-related matters in the Teachers' room.
