Aliasing tahliansfm → tahlian
Link to alias

Reason:

It's redundant to keep the SFM part if I'm no longer working in SFM.
I rolled with the name because "Tahlian" wasn't available on Tumblr and DeviantArt when I started. Newer accounts on sites use the name Tahlian.

tahliansfm_(artist) → tahlian
tahlian_(artist) -> tahlian

I don't believe you really need to give a reason if you want to go by a different name, do you have any other names that you go by/have gone by?

Also, looking at your profile I feel it appropriate to
infrom you of your artist wiki,
https://e621.net/artist/show?name=tahlian

You can have this connected to your profile as well if that is something your interested in by asking an admin, or possibly one will see this and do it for you if it is something you're interested in.

Still felt like pointing it out for completion sake :p

I only used Tahliansfm and Tahlian.

Connecting it would be neat. This reminds me that I should update my profile here too.
