This is a replacement for the WowHeroes support that was in WowPhpToolsWebService
If you encounter any bugs, or have a feature request create a new issue at github.
For support feel free to ask me using twitter @cbaartse.
You can download wowHeroes.js here. However you will need jQuery to use it to the full potential (without jQuery you have to manually do the ajax request).
The throbbers as seen in the examples can be freely generated at ajaxload.info
Currently there is no way to fetch just one character only full guild rosters.
