In attempt to set up a calendar on a newly created site I discovered there is only a single option.
In order to create access to an online calendar one needs to have Office 365 or ical configured.
Not all GoDaddy client have access to Office 365. For those individuals that do have access to Office 365 calendar, they may be using their calendar for personal reasons which are not related to their website, hence the need for calendar alternatives.
There needs to be a means of incorporating a series of generic editable calendars into GoCentral.
