Hey,
I was expanding some character tags into full names and I thought about the idea about aliasing the originals into the new ones. Now, I saw that aliases are admin-approved only, so I got stopped with this.
In my opinion, if some characters have full first and last names and their first are unique enough then those could be aliased freely to their full variants. I know about the character_(owner) format as well but that usually applies only if someone has multiple characters with somewhat common names and not single main fursonas.
