User blog:Flower1470/Bookmarks and profile

Hi! Two things:

1. I've been "Bookmarking" alot of pages here; is that allowed?

2.I logged on today, to find on my talk page that where it says "I live in___", "aka___" and "favorite wikis" is in gold. Just yesterday, it was white. What happened?

Sorry for all the questions, I'm new to the "wiki" thing!
