Ahoy mates, a friend just had permission of something they were doing denied, although its been in the works and things looked very good( i cant go into it here in detail ). someone is doing their best to screw them over and we believe we know who the person is.There are some other areas that are being gone through to try to remedy the situation but what could one use here to get the person from meddling further. any ideas ye folks of mighty resources,heheh.
Thanks
