Yes, it's within a block tag called "content". It's a stupidly simple
base template right now (I haven't turned any of this loose on the
designers yet):
<html>
<title>{% block title %}{% endblock %}</title>
<body>
<div class="header">Header</div>
<div class="sidebar">Sidebar</div>
<div class="content">{% block content %}{% endblock %}</div>
<div class="footer">Footer</div>
</body>
</html>
The template that's trying to display the messages attribute is
similarly simple:
{% extends "base.html" %}
{% load i18n %}
{% load account_extras %}
{% block title %} {% trans 'Account Preferences' %}
({{ profile.username }}{% endblock %}
{% block content %}
{% if messages %}
<ul>
{{ messages }}
{% for message in messages %}
<li>{{ message }}</li>
{% endfor %}
</ul>
{% endif %}
... other content follows, but it's just the form stuff (the form I'm
passing from the view *does* appear/work as expected). In fact the
entire template behaves properly except for showing "messages". I can
edit values and save changes just fine.

Sorry I wasn't more clear on this :) I'm referring to the output
provided by django-debug-toolbar. When I view its "Templates" tab
(after saving the form, the same form is displayed again (for more
editing), so there's no redirection here that could be munching the
message), it displays four Context Processors:
* django.core.context_processors.debug
* django.core.context_processors.media
* django.core.context_processors.auth
* django.core.context_processors.i18n
For each one, it can display what's assigned to each one, and within
the auth context, it's showing:
{'messages': [u'Preferences saved.'],
'perms': <django.core.context_processors.PermWrapper object at
0x01819350>,
'user': <User: wferrell>}
Now that's a little different from before (previously, messages was
just [] (empty)), but unfortunately the {% if messages %} bit in the
template still acts as if messages is empty.
Note I'm not actually setting messages anywhere; the documentation
suggests (at least to me) that it's supposed to be set automatically
by the auth middleware. Should I be explicitly calling
get_and_delete_messages() and sending that to the template myself?
[Update: the answer to this is "no, let the middleware do it". See
below.]

I didn't realize that could happen ... funky. Though this hasn't
solved the problem I'm describing, I'll make sure to keep this in mind
as I roll out more templates. Thanks for the pointer.
*sigh* I was just about to post this as-is, and tried one more thing,
which fixed it. I hadn't added context_instance=RequestContext
(request) to the end of the render_to_response() return in the
specific method I was working with. I'd added it to a different one
instead. It's fixed and working -- I'll put on a dunce cap and sit in
the corner until I've learned my lesson :)
Thanks again for your help.
