So how do I update me timeline with this new system?

One way is to click on your name and update your signature after it goes to your stats page. If this is what your asking about the timeline that is below your posts. Good luck.

another way is to go to 'Immigration Timelines' at the top of the page. On the left hand side you will see

Timeline Functions:
Edit / Add my Entry

That's is! Thanks.

Seems it was easier to locate before?
