Links to other sites are as simple as links to pages on AllAbout. Place the full URL between a single set of square brackets. To add a title to the link, add a vertical bar, then type the title.
Here are some examples:
* [http://gmail.com] * [ftp://ftp.openbsd.org/pub/OpenBSD/] * [http://weatheroffice.ec.gc.ca/city/pages/on-82_metric_e.html|Kitchener-Waterloo Weather]
If you don't mind the link liiking like a link, you can just type it into your text and if it looks like a link, it will be converted into one.
* www.allabout.com * ftp://ftp.example.com/pub * http://goober.com * frogs.com
