[development] Categorizing modules-demonstrating the value ofthe Drupal platform

> Turn on free tagging and let everyone suggest categories as desired.

Thanks Moshe, it's a good suggestion.  The way we've coded this in 
project.module, though, is that the projects vocabulary is used in a special 
way: the top level terms are project types (Modules, Themes, etc.).  This is 
what allows us to have a local task (tab) for each project type.  Second+ 
level terms are the options for that project type (e.g., Modules might have 
mail, XML, etc.).

Am I right in thinking that freetagging always creates top-level terms?  If 
so, that won't work here because of the specialized use of top-level terms.

One suggestion has been that we could have this specialized (and manually 
maintained) vocabulary, plus another freetagging vocabulary.  This permits a 
vocabulary with a select, limited number of terms, plus a larger 
community-built one.

If we want to combine them, I suppose we could either:

* use a different vocabulary for each project type (this would require a 
fair bit of recoding)
* use a modified autocomplete, sending a designated parent term, so that 
projects with 'Modules' as a first-level term would create second-level 
child terms of 'Modules'.

Alternately, we can simply create a second, freetagging vocabulary, to be 
used in the interim to gather information that will be used to manually 
create categories.

Or we could return the designated project vocabulary to having just 
first-level terms, and use other vocabularies for categorization.

Thoughts on what would work best?
