But it is very inconvenient if your click on the calendar and manually click it back to year 1970 or so. If u want to manually type it it the box, the box doesn't even show the full format guide line in it. And I asked this question before but haven't got a reply yet: How to change the format to DD-MM-YYYY.

Is there anyway to make it more user friendly like vbulletin. This would be the much easier for user.
