For that percentage of completion of your profile, I should have more done. Haha. It said something about posting 3 blogs within a week margin, and i know for a fact that I did just that. And, how the hell am i supposed to have 5 close friends when I don't know anybody, personally, who has a UG account? haha blah-blah. lame.
actually, to add someone as a close friend, simply go to your profile (where you edit it) and in the user menu, right under pictures is "my friends." click that. then, it should give you three options, click the third one, "edit friends" and check which ones you want to edit. then, scroll down to the bottom, and click "make a close friend" and then they are changed to close friend. i don't think there is any way for them to even know that you made them a close friend, and as far as i know, the only thing being a close friend does, is when you post a blog you have the option of allowing everyone to see it, friends only, or close friends only. though there may be something else.
anyway, good luck on getting to 100%. i'm at 86%. i have 100% for everything except for 43% for "my band profiles" and 0% for "my contributions."
