Anyone know how to contact Forest Johnon (He may be working for UT)

Just wondering anyone know how to contact Forest Johnson?
Since his Asset Store account doesn’t has any email address, I am wonder is there a way to contact him?
I ran into couple of problems in one of his Asset Store asset (Sprite Packer with Legacy Particle Emitter to Shuriken converter)

EDIT: Nevermind. I found his forum account.

Valid support email must be a requirement for anyone willing to sell anything on the Asset Store.
