[Chameleon] Remote Template/context document question, and potential code con tributions

[Tyler Mitchell]

Chris,
If you find bugs, the usual method for sharing fixes is through bug reports.  You can access the Chameleon bug reporting site at:
http://maptools.org/chameleon/index.phtml?page=bugs.html

Then you can attach your patches in the report and then one of the programmers who has access can check it out and merge it into the base code.

Glad to see any B.C. forest-related Chameleon user!

Tyler
