I have made the payment and initially tried with existing user id "sadaetikala"when lab was in preview mode,but no luck. Then I had requested to clean up the user by mailing to itversity. i was told that it was cleaned up and was asked to create the user id.
it looks like the user id create option is available ONLY at the time of payment.
Please let me know the options to create user id as I can’t find the option.
Do let me know if you need further details.
Thanks and Regards,
