I had a fun experience with Kent State:
Their Grad admissions department for the university has different requirements than the SLIS. No biggie, that's typical.
However, the SLIS, which you would think would be more on the ball technically, required paper versions and signed forms from recommenders.
The general grad admissions site allows direct uploading.
When I contacted SLIS, they assured me that people could submit online and they (SLIS) would still receive them.
Just to cover my bases, I had one recommender mail a paper form as per the SLIS website instructions, and the other 2 submitted online.
NONE of them have been received, despite all of them being mailed before mid January.
No one can explain why this is, and the grad department at SLIS informed me that I must have done something incorrectly. They also refused to resend the email link for my recommenders to submit their letters online :/
