The Rivet mailing list is the first place you should turn for
	help. If you haven't found the solution to your problem in the documentation  
	or you have a question, idea, or comment about the Rivet code itself send email to
	<rivet-dev@tcl.apache.org>. To subscribe to the list, post email to
	<rivet-dev-subscribe@tcl.apache.org>.
      
The mailing list archives are available at http://mail-archives.apache.org/mod_mbox/tcl-rivet-dev/
The news:comp.lang.tcl newsgroup is a good place to ask about Tcl questions in general. Rivet developers also follow the newsgroup, but it's best to ask Rivet-specific questions on the Rivet list.
There are several web sites that cover Apache and Tcl extensively.
Apache Rivet uses the Apache Bug Tracking system at http://issues.apache.org/bugzilla/. Here, you can report problems, or check and see if existing issues are already known and being dealt with.
	Rivet makes available code for two popular editors,
	emacs and
	vim to facilitate the editing of
	Rivet template files.  The key concept is that the editor is
	aware of the <? and ?> tags and switches back and forth
	between Tcl and HTML modes as the cursor moves.  These files,
	two-mode-mode.el and
	rvt.vim are available in the
	contrib/ directory.
