Decided to pull up this thread b/c it's the same things I'm wondering. I asked and gave my professor all the necessary forms months ago (like in March) and I've followed up with him by email before I left school for the summer (he wasn't teaching this semester but he's been out of his office for long stretches of time), but he still hasn't sent out my letter. I think I gave him enough lead time (maybe too much, he might've forgotten) to write the letter, but I know he's also been really busy this semester. I won't be able to meet with him this summer (just too far away), so how should I ask him to write/send in my letter ASAP (by email or phone)?
