Wiki working

Now that I have worked and helped complete a webquest on Pbwiki, I feel confident in this new technology. However easy this service is to use, it is also severely limited and not very powerful of a publishing tool. While the actual page has limitless potential for the experienced programmer (as there is opportunity for open source--there are a few publishing tools that do not allow open-source editing), the format around the page seems unalterable. Perhaps there are tools in templates that I haven't looked at, but it was very frustrating to be limited in this way.
