New skills? Hah! Simple enough, I'll help.
Go into the SKILL's tab on the database and click Change Maximum. Just change the Maximum to lilke, 999 or something lol.
Now, off to the right is everything you need to do - choose a name, description, scope (who it's going to affect), SP Cost, etc.
All you have to do is just fill that out to your desire, and just test it out to your perfection ^^
Hope that helped
