WebCalendar Wiki - Introduction

WebCalendar is a web-based calendar application. You can configure it as a single-user calendar, a multi-user calendar for groups of users or as an event calendar viewable by visitors. Not sure what a Wiki is? Read this. The purpose of this wiki is to allow WebCalendar users to provide feedback to the WebCalendar community. Did you find that the core WebCalendar documentation didn't cover something you were trying to do? If so, then add the documentation to this site on. (You will need to create a wiki account to add or edit content.)
