U-232 Failed Login System

[wizkid08]

variable $_232 is my custom addition rather then use the original variables I have been giving my copy some minor to major upgrades. I may not use memcache yet but I am building my first custom Beta 5 v3 in the future already as I build my current one to u-232 v3 standards as I love its potential in development wise. I will learn memcache just so I can add it into my builds for the future but have it commented  out but thats my way to learn any programing languages anyway. I don't intend to sell my source as I only believe in M.I.T License, I do however do offer my service to help anyone in the community for $15 setup sources and work for a few days & remember each 2nd $5 made in profit will go back into this premium support forum.
