As a matter of fact I had created an account in the past but I didn't go any further than registration. I didn't fill up my profile, at all, I never used it. I never even logged back in. So just out of curiousity I logged back in just now and nothing has changed.
The recruiters never told us to create a profile if we didn't have one and I don't even recall them asking if we had one.
By the way, things seem to be moving quite fast!
I had my AD on the 7th in Melbourne and my FI on the 9th. I got the tattoo form yesterday by e-mail and I just got a call from Dubai.. Not a GC tho
They needed more information because I hold 2 passports. But I take it as a good sign!
