Scorpio can confirm or correct this but, I think that you can make updates to your profile at any time. Then put a message in your updates or signature line to refer to profile for location.
I certainly would like to know where Kylie is on any given day ;-)
You can post once every 7 days in Weekly Updates forum, and once every 7 days in Weekend Updates forum. Ladies commonly post on Thursday in the Weekend forum, and then on Monday in the Weekly forum.
You can also make posts in the local Weekly Update and Weekend Update sections for whatever city you are in. Maybe participate in the local Coed and Sandbox forums to let people know you are in town too.
