@Tim_B reported me just 10
@Tim_B will send you a message when he has a moment to do so. Spamming the frequency should be one of those things that you simply don’t do. If you don’t get a response back in say 5 minutes then you’re safe to send another request so long as you haven’t received a response back.
If; however, you were told to do something and/or denied your request, only to ask for the same thing again, that’s spamming. Once a denial is issued of some sort, you don’t ask for it again. But he’ll gladly explain the situation to you via PM.
