Another one of these threads....
That's NEARLY IMPOSSIBLE since:
EXP is SERVER SIDED meaning you have to hack into the server or use a packet editor.
Please refrain from posting threads like these since this forum is already littered with requests that can't be fulfilled because the ones that request them fail to search around and research about the things they are requesting.
I don't want to post any links to these exp hack threads since I don't want to embarrass those who want to keep their failures from resurfacing.
