Site Optimization Project

Script Optimization which Include Following :- 1) Coder will check all files in script for optimization, security holes 2) Mysql Optimization ensure that the mysql connections are properly closed after execution of the query. 3) Many users who are using IE 5 or 6 non updated version or are using firewall i think can not login, they enter username and password but script redirect them to login page without any error log, this was the script core issue, the only solution i am using uptill now is recomending my member to use Firefox, but i want you to change or update the login code of script and also add "Remember Me" Feature.
