is there any way i can convert my wiki to a 1.0 instead of a 2.0?

This is a common comment while pbwiki 2.0 is still maturing. In the mean time, you could use the utility found here: http://getsatisfaction.com/pbwiki/top... to move your content from a 2.0 wiki to a 1.0 wiki.

Unfortunately, you'll need to create a new wiki in order to house the 1.0 content, it can't have the 2.0 wiki name. Additionally, if you're paying for your wiki, you may have to cut a special deal to have your money go toward your 1.0 wiki instead of the 2.0
