Dead Period Questions

Stallion, or anyone else, know exactly the contact rules for Dead Period ? My understanding is still can have some contact but it is limited to 1 call or communication and not daily face to face contact.
I'm curious because coaches from Tulsa, Okla. State, UTEP and TCU have been hot this week at Madison talking to a few kids, including Nate Askew who is the kid who caught 4 TD passes last week to bring Madison back against Smithson Valley in the 4th Qtr. Askew is only a sophmore, but he is 6'3'' almost 200 lbs. and looks like a man against boys at this level. His size as a sophomore is what has Okla State excited.
Madison has to play nationally ranked Katy this weekend still without Devin Thomas (he signed with Arkansas) or his backup, and is missing 2 other starters so I expect Katy will win easily. However, some of the kids were told coaches would contact them after the game on Sunday. Is Sunday contact okay, or not allowed in this "dead period."
