Add 2 items to joomla site

1. Add cookie security to the site When a user logs in the first time, add a unique cookie, save it in the server for time specified (configurable). - If the user tries to login from a different computer who doesn't have the cookie within the time limit - block the user - If the time limit passed, send a new cookie and save it in the server * Note: admin should have an option to clear the cookie for specific users in case that they will report a computer change (after clear, they go through the same process) 2. Open read-more in a lightbox We have a button to buy item, if the user already bought it, it should open the read-more page.. but we want it to open in a lightbox instead. We will need other implementations in the future.. we are looking for good joomla team mate!! * Note: the site is in hebrew, but you will be guided step-by-step and there is no need to know hebrew for those tasks Thanks, Ika, CTO
