@rakman - I just spoke with the prof at Boulder today and she said they have made all their decisions and are finalizing TA assignments now, and we should all hear from them in a week or so. So almost there! And yes, she confirmed funding is low, there are not enough TA-ships to go around, but if I dont get one there is always alternative funding if you can get a bridge til the big grants arrive...
I don't know anything about phone contacts though. Did you apply to work with specific prof at Boulder? Good thing you have those backups!
