[Gnu-arch-users] user id?

[Michael Hanna]

tla archive-setup myProg--mainline--0.1

gives me:

* creating category address@hidden/myProg
arch: no arch user id set

yet there's no command to set my 'id'..
tla my-id foo

my-id: invalid id (foo)


there's nothing in his tutorial on this and the documentation is sparse 
in this regard. Help would be greatly appreciated.
