So curious if possible on this cheaper pj. Well will be hopefully getting things started tonight, but yes when time permits, and believe me I know all about the time, I have 3 little girls and a teenager, and work full time and try and maintain a VDR website lmao so I know all about time lol, please do let me know of any patches etc I might need. Thanks again.
