Test User ID creation in IBP SCI

Hello,

we are using 1802 version.Can some one please guide me, how to create test user ID's in IBP system? We want to create few test ID's and assign them relavent business roles for testing purpose before going with the actual user ID. But with SCI, user will get activation link via email. So can we user personal email(ex:gmail)?

Thanks,

Kishore
