Why can't I create a nickname in yahoo360?

It happened to me many times. 1. If it happen, click red X mark to close that window. Then try open your page. Sometime, your previous action has been done. 2. If not try to do something, you sure that will continue. Then do what you want again Example: Sometime I add a video to my blog, it says: You must add jpeg image or write something or sometimes when i've done, click OK, it just refresh to the same page again . I've changed and add another video and post that. After it posted, I edit them, change the link to the video that I want to show. And it worked. 3. If it continue do the samething again, send feedback to Yahoo. 4. Good luck My360: http://360.yahoo.com/hieu169

And sometimes the page comes back cuz of the birthdate section. Is not working right or something, so leave it blank for now. I finally figured out how to fill out the birthdate properly, but doesn't show up on the 360 pages anyways.
