That's great!Yes, I'm aware of this rule change. Since my profile was created after 1st Dec and MSBTE does not send the documents to WES themselves, I am going to courier the documents myself from Fedex/DHL service near the MSBTE office and put the MSBTE as the sender instead of myself. This is what many people have recommended/done on this forum.
Let's see how it goes.
You might already know this, Mumbai University stamps on sender's address now and asks you to courier it. Just check if MSBTE is ready to do the same.
