Sadly I was away from my computer during the last validation period because of that I have failed the verification. Can I re-apply to get verified using the same address or I will have to use a different address this time.
Thanks
No matter what happens you keep the same address (deposit/withdraw/priv key)
If you were candidate or newbie than you need another invitation. Always, if you are not sure what you are supposed to do, check your current task.
