UB sign up bonus question

[Leavenfish]

Say, does anyone who plays at Ultimate Bet know if the sign up bonus expires and if so after how many days?

I was looking at putting 1K in and getting a 40% bonus to play off at $1/2 and some $2/4 but can not find the answer to this.

For that matter, does anyone know of another site that might have very long or unlimited times in which to clear a sign up bonus?
