Hi all, I'm really confused about how the LOR process works. Granted I'm going to be applying next year, but I just want to make sure I'm prepared with my LORs (I don't want to wait till the last minute to ask for them). First of all, do you guys recommend that I submit my LORs through the AADSAS? I'm not even sure how it works but from my understanding, you give AADSAS your professor's e-mail and they send them a LOR form to fill out, and then they send it back to AADSAS, who then sends it out to all the schools you are applying for, am I getting this right?!? I have also heard of students having their professors send LOR directly to the school...isn't this time consuming for the professor because they'll have to send out a bunch of LOR to different schools??? 
Also, if I start asking for LOR now (remember I'm applying next year) what do I do with them? Keep them in my sock drawer?? Because I can't send it anywhere at the moment... OR should I wait till it's closer to next year to ask?? Also, does it matter how old the LOR is?? Say, if it's like 2 years old, does it matter?? I'm so confused!!!
What's the best way to approach this??
Thank you guys.
