the only "timeline" i can think of would be your post history (202 total posts, 5 best answers).
as far as "tags" are concerned, the only ones i can think of would be the ones you can add to a post right below the title of the thread. however, you are only allowed to add a few relevant tags, not everything you can think of there. or perhaps you meant badges?
again, i am not really sure what you are referring to. please try explaining it in a different way since i believe due to language barrier you are just not using the right terminology.
