Using delay in the mix

[LzR_B3Ak]

First off the introductions: Hi I'm LzR_B3Ak (more commonly known as Steve). Please check and and give feedback on my remixes at http://www.fixtremix.com/artist/bdc6a1e59b4a/.

Can anyone point me in a tutorial on how I should be using delay during the mix process? I think of got the hang of using reverb to glue together the mix and provide a sense of depth but I'm not sure how you're supposed to use delay for the same thing.

Cheers
