It's hard to give tips as I'm not sure what you mean by exciting.
One of very nice ways is to set it to overlay (or soft light and then duplicate layer) when text color is white or very very light shade of main sig color and putting a shadow underneath it with 0 or 1px with bigger spread and 1px size.
Other way is to leave sig plain color on normal layer style and have drop shadow (1-2px away) on normal setting with similar color from the sig and have outer glow on normal too, color black with just 1px setting.
And the best is to take your time, look at all tutorials artists have made and also just google text PS tutorials. Make them, a couple, and you'll learn tons And will find your fav text style.
