Another cool feature is that you can include dynamic blocks in Wiki pages. Dynamic blocks are configured as admin using the Edit dynamic content feature. Basically a dynamic content block is some text that is programmed to appear from a given date. You can include dynamic content using:

{content id=1}

That will display the current value of the dynamic content block with id=1 Or

{rcontent id=1}

That will display a random value for all the contents defined for the block with id=1 (ideal for cookies or taglines!!)
