Return of Reckoning

I feel stupid for asking this, but I have been roaming around for 1 day without luck.

I bookmarked a thread, and now I can't find where the bookmarks are to find such thread again, and in the way I discovered that I simply have no idea of how to actually use this forum, like in example placing a text in the center instead of in the left side.

Is there any actual guide on the forum utilities out of the FAQ, that I have read three times entirely? Or at the very least, can someone point me out on how to see my bookmarks?

Thanks to all
