About Steve Slevinski


Thank you for checking out my patreon page.  SignWriting was created by Valerie Sutton in 1974.  I've been working with Valerie Sutton since 2004.  We chat every Saturday and enjoy working together.

My name is Steve Slevinski.  I am currently the system administrator of and the associated infrastructure. 

Thanks for reading,
