I'm experimenting with some of the free modules that Community Server offers for this platform. Here is how to use the Wikipedia module. Wikipedia is a fantastic encycolpedia that is based on the collaboration model.
To insert a wikipedia link in your text, use the following tag:
wikipedia: TOPIC (surround it by the brackets [ and ])
where TOPIC is the text you want to both display as a link and link to within Wikipedia.
Example
-------
For example, to link to information about the Red-tailed Hawk within a post, you would write:
Last weekend, I had the pleasure of seeing a wikipedia: Red-tailed Hawk with [ before wikipedia and ] after Hawk. (If I put the brackets where they belong you would not see the text.)
So it would appear like this:
Last weekend, I had the pleasure of seeing a [wikipedia:Red-tailed Hawk].
Now when you click on the yellow text a little window will appear with the definition of the Hawk taken from Wikipedia.
