Ofcourse they are coming too fast...

pawn Code:

SetTimer("msgs", 30000, true);
SetTimer("msgs1", 60000, true);
SetTimer("msgs2", 90000, true);

That will cause "msgs" to appear after 30 seconds.. Then It repeats, which means msgs & msgs1 will come at the same time again.
Then msgs & msgs2 will come at the same time again.
Then msgs will come 10 seconds after msgs2 again.

xD
Set "msgs2" in timer "msgs", and "msgs3" in timer "msgs2", "msgs" in timer "msgs3".
