Non-SysAdmins ... proxy account

Error:
Non-SysAdmins have been denied permission to run
replication jobsteps without a proxy account. The step
failed.
&&
Executed as user: Jobz. Replication-agentclassname: agent
cb-desktop\cbx-NEWBIE-NEWBIE_pub-CB-DESKTOP\CBX-9 failed.
Non-SysAdmins have been denied permission to run
replication jobsteps without a proxy account. The step
failed. [SQLSTATE 42000] (Error 14151). The step failed.
What I have:
Calling a Job with user 'Jobz', 'Jobz' owns this job so it
IS getting called.
2 of the 3 steps are failing because 'Non-SysAdmins have
been denied permission to run replication jobsteps without
a proxy account'
How do I configure this proxy account so that running
replication jobsteps will succeed with a user other then
sa ?
Thanks,

I don't think http://support.microsoft.com/?id=818552 is
the solution to this problem.
How do you make it so that Non-SysAdmins are allowed
permission to call replication jobsteps ?
(sql server 2000 sp3)
is this the best way for a client to invoke a merge agent ?
