This plugin is a really simple way to add the Google Latitude “Where Am I” badge code as part of your sidebars. V1.03 fixes a trailing Anchor tag that wasn’t closed properly. In addition, thanks to Dennis Wu (http://denniswu.com/) and Phil Bridges (http://philbridges.com/) for helping to find that SOME users will have a “-” in front of their Latitude id.
This plugin is available for download to be used on your WordPress self-hosted installation.
