Yes, there are two options for additonal fields

Option lists (menu option Rescue Organization Manager -> Option Lists)

If the field is for a defined set of options create an option list, an option list can be defined as a single select list (i.e. radio buttons) or a multi select list (i.e. checkboxes).

Fields (menu option Rescue Organization Manager -> Fields)

This feature provides for fields of type single line text, multi line text date, date & time, currency, number or phone number.

When adding a custom field or list you define which section (tab) on the edit page the field is displayed on and by creating your own custom groups (menu option "Rescue Organization Manager -> Data Groups") you can add you own sections (tabs) to the edit pages.

Custom fields or lists can be added for members, contacts, assets, events, participants added to an event, assets added to an event, event claims, event subjects and event teams and the same field or list definition can be used on one or more to prevent the need to create duplicate fields or lists.

The simplest way to create a new event is to click on the day of the event in the calendar page.  Alternatively you can use the Create Content option on the main navigation menu.

When editing an event there is an option called "Repeat" (where enabled and permissions permitting).  Selecting this option will allow you to specify a schedule by which the event should be repeated.  VolunteerRescue will then automatically create events up to 12 months in the future based on the schedule so you do not have to add the individual events.

When viewing the calendar in VolunteerRescue permissions allowing there will be a button titled "export" to the left of the current calendar month and year.  Selecting this export option will display a link that can be added to any iCal compliant calendar application.  Once added to an iCal compliant calendar any events that are shown on the VolunteerRescue calendar will also be displayed on your personal calendar.
