ditto happened to me. their dept website was not clear about if i should contact the profs before, or after the application, or if i should contact them at all. it's partially my fault that i wasn't proactive enough, and didn't contact my PoIs. but c'mon. the dept should be very clear about the process too. not like we are oracles or gypsies! - how the hell do we know what the next step is.
anyway, i contacted a couple profs whose research interested me the most, but they weren't taking any students. dead end. they suggested that i transfer my application to a similar program in the same college, but i said no thank you. i also found out, very late, that i wasn't given funding because the head of the dept and the guy who is in charge of allocating funds for new grad students, are not in good speaking terms. i was like WHAAAAAT!? they are playing with our future man!
/end soapbox.
