First, a userlookup is where visitors see your stats. A boring one makes you look like a Newbie. To view a screen shot of one, click here. That is a pretty boring and simple one. You can spice one up with a Userlookup Layout.
Where Can I view My Userlookup?
If you are logged into Neopets, on any page (except for home page), click on your username that is on the top banner (below the ad.)
I Chose A Userlookup!
Got one picked out? Good. Now, where do you put it?
Make sure you are logged into Neopets. Logged in? Okay.
Neopets.com>>Boards>>>User Prefrences
Or Click
Here.
You are now at your user prefrence page. Scroll down to the box where it says "About Me". Paste your code in there. Scroll through it to edit your links, about me, etc. Make sure you put your password into the spot where it says "Current Password" because that is required for making changes. While you are here, you can edit some of your info. 
Once you are done editing your info, click "Change Your Details" and viola!
Userlookup F.A.Q.'s
Can I add a shield to my userlookup?
Yes. You can add a shield. It can say things like "Cutie" or "Plushie Queen" but it cannot give a fake account age. For example, if your account is only 3 weeks old, you can't stick a shield on there that says you are 34 months.
Is it ok for me to get rid of links?
No! That goes against the terms of Neopets. All the links found on the side naviagation must be visible in some form. Whether it is a sidebar or basic links.
Can I Get Rid Of My Stats?
No! That can get you frozen. TNT forbids hiding your stats. All stats must be visible.
Can I add banners, blogs, backgrounds, muisc, etc. to My Userlookup?
Yes. Neopets allows these things. You can find banners, blogs, backgrounds, and other graphics here at NeopetsGuide. We do not give out music codes because that is illegal.
