Ryan Dewalt (also known as Tet Solfire) is a jack-of-many-trades, currently living in southern California. His fursona is a "folf" (wolf/fox mix). He has also utilized a rabbit fursona known as Timebase.
He is best known for running a number of furry sites, including the YNA (down as of mid-2009), the AnthroArchives and 17Cats. He is also the webmaster for Kittenbreak, and provides hosting for the Jack on pholph.com and Carpe Diem webcomics.
Ryan is an administrator for the Anthrochat IRC network.
He does lettering and additional writing for Vinci & Arty, which is written and drawn by his wife, Candy. Ask Arty is an associated site, although it spun off more from a similar feature on the YNA site than from the webcomic.
