What exactly is a reload bonus?

Didn´t get much attention at the online poker rooms forum so I´ll try to post my question here:

Do the poker rooms offer you reloads if you withdraw all your money? Or is it only when you´ve lost it?

They will offer you reloads if your account goes down for any reason, be it losing or cashing out. If you played at one poker room quite a bit and then stop playing and cash out for some time, they will usually offer you a reload bonus to come back.

I have not figured out a formula for "reload". I get reload bonus regularly from party even if balance is over $1000. The sites have a regular schedule for reloads that reward regular players. Absolute has one about every week. Interpoker has one every month.

So, no you don't have to withdraw your money and you don't necessarily have to lose it all either.
