Wiki on a Stick has most of its syntax common with the Creole specifications, while some parts remain custom like Email-style emphasis
Our position towards WikiCreole is the following:
There are features which put Wiki on a Stick apart from other wiki rendering engines (it is a pure javascript rendering engine, for example), like our reserved namespaces features (which are really trasversal).
For the rest of the syntax (think about tables for example) a possible unification during the v1.x development cycle (by that time more Creole additions will be out) is wanted.
Our main interests to be endorsed and promoted inside the WikiCreole project are about simplicity and intuitivity; we plan to merge our syntax at some future point of the development timeline.
The current versions of WikiOnAStick (v0.9.x-v1.x) are mantained by DanieleC.
