There is no "archives" tag under this system, regardless of display style, unless you tag, for example, an archives:meta post both "archives:meta" and "archives." You can see the difference in my tags, where, for example, there is no "rpf" tag (you can't click on it and see all rpf) but there is a "due south" tag (in addition to themed tags) that lets you see all due south recs.

A single-tier system (including some suggested revisions) might look like

admin
archive history
coding
content
design
feature discussion
feature suggestions
funding
legal issues
meta
moderation
other archives
other issues
people & volunteering
resources & maintenance
tools and software
universal access
users & community
weekly summaries
