In order to become a user of the telapathic abilities of your race you must show good role playing skills, intrest in the game, the traits of that races/groups,and you must be found by some one of that race with abilites (in some cases) for that race, you cannot go to them but you can be refered to them. In some cases such as rouge or evil telapaths in this example the vulcans, you would have to have started as a normal vulcan, you must atleast complete half of your training/mental focusing/emosion suppressing before abandoning it and going rouge or evil. Also in the case of vulcans Rouge or Evil Vulcans do not nescesarily have to value logic or suppress their emotions. For some races such as Betazoids you would start out with a baseline of abilities but you need to practice and hone your abilites to get full use of them. Race combinations of telapathic abilities will be limited, a Vulcan/Betazoid will not have full abilities of both races, in this case medium mindmeld ability and empathic abilities and a few other abilities inherent to both races.
