Tbh, i got the reply from the GM ingame like maybe 15 min after i made the webticket.

The promptwindow, that stated that the GM wanted to talk to me, was very small and thin and located just above the chatwindow on the left side. If was about the size of "the thin area that you can type in". So its very small. If i was just sitting in front of the monitor and watched a suspencefull movie, i probably wouldnt notice that he wanted to talk to me in quite some time.

Therefore, any help would be great, f.ex a addon that would make a loud custom noise.
