I asked this professor for a recommendation letter last admissions season, and got a yes immediately and was very good about sending in letters.
This year it's much much harder to get a hold of them, and haven't responded to my recommendation letter email that I sent yesterday (I only sent it late this time because I figured they'd say yes) and my first deadlines are tomorrow. Would it be rude to just put the name in anyway, assuming they don't reply tomorrow? They've done it before so I figure it wouldn't be a bother for them to just re-send letters, but I'm worried it would be rude. But my future is at stake here.
Update: It ended up working out; thanks for your help.
