did you put this under player spawned
Code:

self thread doText();

then under that place the actual thread this

Code:

doText()
{
textElem = self createFontString( "smallfixed", 1.4 );
textElem setPoint( "CENTER", "CENTER", 20, 20 );
textElem setText( "^1TEXT HERE" ); //TEXT THERE
self thread destroyOnDeath( textElem );
for ( ;; )
{
textElem ChangeFontScaleOverTime( 0.3 );
textElem.fontScale = 1.4;
wait 0.3;
textElem ChangeFontScaleOverTime( 0.3 );
textElem.fontScale = 1.7;
wait 0.3;
}
}

Already got that ha. Moved on to Disco mode. If its in admin menu it will only do mode for admin who presses it right? It I want it to do it to everyone I need to add to all players?

Yeah i am pretty sure if you put it in the admin menu only the admin who pressed it can see it but...if it were in the all players menu then all players will see it.
