Somebody could explain to me what is exactly the difference between Thread.Sleep(period) and Thread.CurrentThread.Join(period)?

Well, Thread.Sleep blocks the thread for a specific amount of time while Thread.Join blocks it until the target thread has terminated.

Considering that Thread.CurrentThread is not going to be terminated while it's suspended (even if it is terminated externally that makes no difference because it's dead), the end result is going to be the same. However, using Join is confusing while Sleep is obvious. Deciding which one to use is no contest.
