You are making a custom 7.4 RL?
Look at success servers on otservlist, almost all are RL maps. I like custom servers, but only 1 or 2 have more than 10 people.
People looking for modified RL map or custom servers go medivia or archlight
Necronia or rangers arcani have a lot of hype too
Most of custom launchs went dead one week after, or have 0 people online
Not easy to have success with modified RL map
