That will help.

If you can keep a reasonable fraction of the new players who actually deposit, you will grow.

If you can create periodic attention-getting promotions, many of your players will post about them in various poker forums.  How about some StarsSucks™ incentive for PLO players, for example?  Consider creating one rotating, rake-free table.  Sometimes high stakes, sometimes low stakes.  We will make it famous.

We want you to be successful.
