We've been faced with a dilemma for a while now that doesn't have any great solution. With the eventual introduction of user pages, user URLs will become much more prominent destinations. For example, I'm hoping lots of people will check out tomfulp.newgrounds.com once it comes into existence. :)
The question is... Do we allow users to change their names at this point? If you change your name, you are essentially changing your URL, meaning all existing links to your page will become dead links.
It has never been a problem in the past because the profile URL is based on your unique ID #. Since user pages will be tied to your name, the only option is to make your name a permanent identifier, otherwise users could create dead links at will and it would make the site a lot less organized over time.
I get this bad feeling that people will totally freak out at the thought of not being able to change their names. Plenty of sites already don't allow you to change your name, but people are accustomed to the option here on NG. Then again, are name changes really necessary or is it a feature that people abuse in the first place?
Consider this post a sort of heads up... There's a chance your name might go on lockdown, so be sure it's the name you want to have. This is also a chance for everyone to share their opinions concerning this course of action. Go for it.
