Improve clarity, get the hippo down off the stilts.  Some improvements
suggested by bjk@.
Clarity improvements, convert the rest of examples using CDATA to
<sgmltag>.
Whitespace-only changes.  Translators, please ignore.
Remove a confusing paragraph whose net contribution is negative.  Remove
some &nbsp; from "Ports Collection", it's unnecessary.  Make one example
section consistent with the actual code.
Use a better word in a sentence.

Remove Upcoming links from our events pages.  Upcoming was a Yahoo!
service for events that has since been turned down and was never used
much by this community in the first place so the links were not that
useful even when Upcoming was available and popular (it is now long
since completely turned down and the links all jus go to yahoo.com).

Meetup.com is the most popular service for upcoming technology meetups
in the bay area at least, and is used by the local BAFUG, but the
links are probably best added manually for events instead of optimistically
adding a link that tries to search on meetup.com for something
matching the event.
