hello, i would like to know on which site you want register,login and than do posting ? after that i can give you specific description. but still here is few thing about my application and working method, i am using .net & c# language to make application. all application will be fast enough in term of speed + works in background + won't eat much of system's memory or other resource, so, you can continue your other work as well while its running. Final work will be provided within given time frame. would like to hear back from you. for my past work kindly refer to my profile page. consider my bid and let me reply if you got any query. thanks, Hardik @ hsCode Solution
