AROCSD member accounts support creating Classified Ads.
To create a Classified Ad, you must log in and select "Create content" to create a "Page".
The "Page Types" available are:
1) Announcement
2) Classified Ad
3) Narrative
If you do not choose the correct Page Type, your ad will not appear in the Classified Ads section.
Please refrain from "promoting to the front page" (uncheck this feature in "Publishing options").
