Well.

I got an answer from Tartu University - they haven't chosen me. Not sure of I am upset or not - this would be very stressful and I am fed up with stresses. But it would be good chance - and I've never been to Estonia. And it's also never pleasant to be rejected. However, it's not the last conference.

I found something that might be interesting as well (another conference - details later) - I need to check the things out and to talk them over with my supervisor before I decide anything.
