Not sure if this has been brought up before, but it would be very helpful to get a notification of a user's name change if you follow them.
For a few reasons:
1) I occasionally go directly to some of the artists pages that I have commissioned before. If their name changed and they didn't know to say something about it/I missed the update/They didn't make an announcement, I am suddenly getting a 'user does not exist' page.
2) All links to them become broken. This could also be fixed if the system went through and changed these things automatically, but I don't know if that is a viable option (I think DA does it, but I can't recall for certain). Besides, if someone has a name that is a common word or phrase and it was a find and replace type deal, that would be messy. Anyhow, a notification of a name change would be a good way to say to followers that have mentioned them: fix your links
3) Especially in the case of drastically different names, suddenly seeing journals/art/etc from a name you don't recognize. Maybe this is a good thing to some? It might make you click on the name to find out who the hell they are, but for me, and I am bad about this, but when I have a ton of notifications, especially non-art, I usually scan for certain names, or keywords, rather than looking at individual entries, and then clear everything that didn't fit the scan parameters (in my head). This is problematic if a name I was looking for was suddenly something else without notification. So even in the above mentioned scenario of someone posting a name change notice, I'm likely to miss it.
Those are just three things I can think of off the top of my head that may or may not have affected me recently.
A simple notification like "User FeyPheonixz has changed their name to FeyPhoenix" to their followers and friends would be great and eliminate most of the problems mentioned above.
Thoughts?
