Hey! I'm a silent reader of this forum for a long time now. I wanted and was planning to open up this thread. Good thing you had initiated ;D
I submitted my full documents on Feb 2011 as well and no 2nd aor as yet....However my visa office is London.
I hope there are some more applicants who have submitted full documents on Feb 2011 so we can connect and share our timeline.
Based from the most posts here, I can say that those who received their 2nd AORs hae submitted their full documents on or before January 2011.
