It is so great to see the community working hard at making their Plugins fully WordPress 2.0 compatible, and SimpleTags is one plugin I just got into when I upgraded
SimpleTags now works with WYSIWYG editors. Tags have changed from
to [tags]. If updating from an earlier version, you need to perform a simple update on the database. Please check db-update.txt in the zipped distribution for detailed instructions.
Jump on over to www.broobles.com/scripts/simpletags/
to get the latest version. Happy Tagging.
