Build a Website

I have a website and i have some errors in my website. I have 3 main works to do all of them are very small tasks. 1. I have forum on help page where we can create account and login but i want that when people login on my website from main account they should automatically login on this page. 2. I have reset password forum where we use forgot password and send mail to mail id and reset password. On my website i can send the mail and when we open link it works very well. After that when we enter new password it's not changing in database and still we login with old password. 3. I have 2 page one is concept other is presentation they both works same. They both re working i have problem that when i save the a new presentation it shows in recently added concepts on concept page. I just want when we add new presentation it only show in recently added presentation and want to remove banner from presentation page. 1st and 2nd task can be done on your local computer but third one is can only be completed on my machine with team viewer because there is lot of softwares configured for video recording and images. I need some one who have good experience in YII, PHP and javascript.
