Bi-weekly scheduling is not currently an option.
The only way I can see it being done now (besides posting each individually) might be to post a weekly recurring event, convert them to 'static' events using the "Split Recurring Event" plug-in then deleting every other one. Sorry.
You can read about the Split Recurring Event plug-in at the Unofficial CalendarScript - Mods and Plugins site.

PS. "Recurring events" all have to have *exactly* the same event details. It is not possible to change the text of a single occurrence which is what the Split Recurring Event plug-in was designed to get around.
