Very insecure.. somebody can type in

\"url $cr quit\"
and it will make the bot quit IRC because it parses $cr as a new command line. To fix this use the n switch in the $read function. Sure this willt ake away bold and colors but it makes it that much secure from identifier attacks. You could always just replace the bold tags with [b] and reparse it when it\'s called via the alias.
For parsing as text (eliminates calling of identifiers): $read(quote.txt,n)

Also Comment out the top part describing the addon.

You also don\'t need the \'/\' before each command.
