I dont know about the rest of you but i could really use a mod that allows me to change my sims name...its getting real annoying

I WANT MY OWN LAST NAME BACK!! lol

anyone else have any wants??

One of many features in twallan's Super computer is the ability to rename a Sim from anywhere, along with tons of other options, tweaks, and various sweet stuff to play with.
From the site:
# Sim...

* Family Tree : Brings up the genealogy window for a sim selected from a list.
* Focus : Focuses the camera on the specified sim
* Dresser : Brings up the dresser CAS for a sim selected from a list
* Invite Over : Invites over the specified sim to the active sims home lot
* Make Active : Allows the user to specify a new Active sim
* Rename : Changes the name of a sim selected from a list.

etc, etc, etc. In one of the mods there, there's an option to set the naming convention for when a Sim marries also..Female's last name, male's, no change, hyphenated... I forget if it's the SC or Storymode mod though.

You don't need a mod for this, just click the city hall, and you can select to change names. You can change both first and last name.

Locking. Not only does this ability exist in game, but there's an earlier "most wanted mods" thread: http://www.modthesims.info/showthread.php?t=348244
