To enter an event go to the month and click on the date of your event or click on Daily (one-day or randomly occuring events), Duration (continuous events over days, weeks or months), Periodic (repeating weekly or monthly). A data entry panel will open where you can enter the details of your event and choose colors for background and text. Entries in the popup field that begin with http://www.domain.com or www.domain.com will create a URL link to your own pages. Text entered in the popup field beginning with anything other than http:// or www will cause a popup window to be created.

I have enabled you to edit the calendar so you can correct your own mistakes.
Please don't abuse the privilege. Do not delete anyone else's entry.
Brevity makes it less cluttered and allows more people to use it. Thanks.
