It’s finally active the possibility to change your SL name and/or surname. You can find it on your Dashboard, Account >> Change Name (before change password).
Specifically, you can freely choose your name, but for the surname, you need to choose between a default list. This list is not exciting, in my opinion.
Also, the price is high: USD 39.99 + 8.80 VAT (I live in Italy, so I have to add the VAT).
I have waited for a long time to change my surname, and now that there is a chance, the default list doesn’t fit my needs and in any case, the price is too high for a name changing.
This time I’m going to jump.
