One Word Wonder

Thanks for starting on time, Professor!

I'll be late for the lecture unless I can get a better idea.

Students are advised to check their individual watches, rather than rely on a large wall clock, which is notoriously unreliable.

[3]Exactly what I needed....

Cute. I got about halfway through when I recognized things.

[3] - Thanks, perfect salt...

I have a vague idea what to do and where to start, but vagueness needs to coalesce before I can solve this!

I apologize that there won't be any hints for this puzzle -- I submitted it before they started with the hints thing and can't figure out how to edit that.

[7] It starts at 1:05. I wonder what might be special about the time 1:05 that isn't special about 1:06 or 1:04. Something that might not be apparent in a digital world.

i had to peek, read the solution, and i STILL can't figure out how this is supposed to work.

[8] ahect, you've got nothing to apologize for; the art work on this puzzle is incredible!!
Did you actually make these posters and take a picture or did you create this in a graphics program? Either way, nicely done.

[10] I created the center poster, found a bulletin board at the local university, put it there, and took a picture.

Supercool.

randomly stumbled on this puzzle. I think it's excellent!
