I have just posted on my web site a simple Absence Submission custom feature. It is a simple but powerful feature that allows organizations to provide their members a way to report absences on their website. It also provides notification emails when Absences are submitted, the ability to purge/clean up old outdated absence submissions, and a filterable grid view of all reported absences.
The source code is also available so check it out. Let me know if you have any questions.
FYI, if any one is interested. I just released a 0.1.0.1 version of this feature today. It contains some bug fixes and some added navigation capability. See all the details on my Absence Submission page.
