Thought I'd mention that today is the 15 day mark to my 90 days report being due so I decided to try the online reporting system.

I logged in using the current release of Firefox, I had to acknowledge the lack of security certificate on the immigration website, agree to the terms, fill in my data (which includes a new address since the last time I had to report...like a year ago).

I printed the pending receipt at 9:50 am and received the approval email at 2:23pm.

Super easy and extremely fast. Best of all no need to drive to CW and find parking. :)
