To do a recurring event, check the Multi Day Event box to add a begin and end date.  In the configuration below, the event will occur each Wednesday from 7-7:30am until May 25.  If you insert a 2 in place of the 1 in the Every Weeks(s) box, it would occur every other week.

 

 

If you wanted to do a monthly meeting, here is an example where a camp meeting is the first Thursday of every month from 7:00-8:00am. If you want the meeting to be every other month, you could put the "First Thursday of every 2 months", or if you wanted the meeting to be once a year then you could put the "First Thursday of every 12 months."
