Linesmen - do you signal your foul?

[Dommer1]

If your conference/league has decided that they want the calling official to give the signal, so that the TV people can find the foul on the tape and have the replay ready sooner, then do it. If that's not the case, get to the R and report it there without signaling.

I too think it was about time to get the numbers included in the announcement in NCAA games. As someone said, the do it in basketball. Perhaps football players are more sensitive than basketball players? Should give numbers in NF as well, but I guess we'll have to wait for that to happen.
