There's a Menu on Profile Stats page where you enter the lat & long co-ordinates of yr position on planet. I had to do it on joining, but went looking again to try to give you the nav but cldnt find it. So I've asked the Help Desk & they'll reply in a day or so & I'll let you know.
You cld go to top of page, left end b4 Deviations & Messages stats & click on down arrow next to yr avatar name & go to the Settings menus & look under General & Personal & enter stuff there if you haven't already. There's quite a lot to this site, but after a month or so u'll get the feel of it.
