Tag it, then filter it
ThoughtFarmer supports free tagging, admin-defined tag bundles and group-editable taxonomies. Filter through tagged content with ThoughtFarmer’s filtering interface.
Free tagging
Apply any tag you want to any page or document in ThoughtFarmer.

Tag bundles
As an administrator, you can predefine tag bundles. You can keep the bundle closed, or allow users to contribute new tags to the bundle.

Tag filtering
With filters, you can quickly narrow down a search to just items with the tags you want.
