PS: I've been reading this forum for some days for updates. Thank you for all those who have shared their info and knowledge. I've thought a few times of sharing my details too - after all this is all crowd-sourced - but after seeing the anger in the comments made by some 2018/2019 applicants who are still waiting, I didn't feel very comfortable. Nonetheless I feel for those applicants, and I hope the backlog is cleared asap with a large scaling up of the new online solutions. Good luck everyone
