My first attempt to contribute to E*Pvp so be nice to me. I've used the search and wasn't able to find what I was looking for so I made this macro. You put your xp skill you want leveled on your F10 key and let the mouse hover or your head on the guild gate so you don't click on anyone else that may be leveling their skills on the gate as well. It automatically attacks the gate, uses xp skill, then attacks the gate again. Used this to level my ND, Fish, and Robot skills on my characters. Hope this helps someone else as much as it has helped me.
