This is because I made a mistake; when I updated all those camps to
point to the new "reskin" repository and pulled in the code to provide
the [template] tag, I neglected to restart each camp's Interchange.  The
code for usertags is loaded in at startup time, so introducing a new tag
necessitates a restart.  I'm sorry that I seem to have forgotten to do
that in my mad dash to get them all updated.

In any case, it works properly for all of them now.

Interchange is there a set of commands to add a new Template to a
catalog? Better yet how does does  [var HEAD] know where to get the HEAD
template from? I have been going through the Interchange documentation
but I have not found an answer. 

Any files in the catalogs/nbp/templates/regions directory get loaded in
with a variable name matching the filename.  So, from within your camp,
catalogs/nbp/templates/regions/HEAD corresponds to the HEAD template.

The only annoyance is that if you introduce a new template variable in
that directory, you'll need to restart Interchange for it to pick up the
new variable.  You can do that from within your camp via:
  re

("re" short for "restart")

> As I understand it we are switching from the ITL [var] tag to the
[template] usertag. Is this correct? 

For this particular usage, yes.  [template] in fact uses [var] under the
hood, after determining from the environment what templates to use.

> Also during our first conference call there was talk of a "Template
Engine" and a Database holding the location of the Template. Is this how
it works or did I misunderstand? I read the documentation available on
the ITL [var] tag - access local (catalog) and global Interchange
variables. 

The "templates" are just Interchange "variables" that have a
layout/presentation purpose (you can use variables for any number of
reasons, of which layout/presentation are among the more frequent
examples).  As described above, IC loads all files from
catalogs/nbp/templates/regions into memory.  It's not really a template
"database", it's more that the directory mentioned acts like the source
for some of these template variables.  That's all.

> In order to gain some experience, I copied a template
catalogs/npb/templates/regions/SUPPORT_TEMPLATE_TOP and named it
SUPPORT_TEMPLATE_TOP_STEVE. Then I modified index.html to use [var
SUPPORT_TEMPLATE_TOP_STEVE]. As you might have guessed, nothing
happened, it did not find the template. So I take it there is a command
or something to add the template to the catalog. 

Just the aforementioned restart.  :)

Thanks.
