Tagging plugin and list of tags

[jasondlee]

Perhaps I'm missing it, but is there a way to iterate over the tags in a site? Using the tagging plugin, it seems that we're given page.data.tagCollection, which shows the tags for a page (I think?). I'm not seeing, though, a collection we can iterate over to generate a list of (unique) tags in the site (e.g., a sidebar listing of tags with links to that tag's page).

Am I missing something, or is this just not possible. Currently, I have "virutal method" on RoqCollection, which iterates over all the pages, returning a sorted list of unique tags that I use in my template. That works, but if I'm using the plugin incorrectly/incompletely, removing my own custom code would be nice. :)
