I want to make 6 changes to my website elancer.mk. It's written in PHP with MySQL. 1.) If a worker makes changes to his offer, I want to employer who follows him to be notified via the javascript (that I have already installed) and via email. 2.) I want the workers to be able to see in a separate column, how many employers are following their offer. 3.) I want the users to be able to chat with each other and I want them to be able to see which users are online. That will appear right under their name. Please check the pictures "online-status.jpeg" and "if-he-clicks-on-chat-with-me.jpeg". 4.) Right now, the worker and employer can send each other private messages only if the worker has bidded on the employer's project. I want the users to be able to send themselves private messages regardless of whether the worker has bidded on a project. And I want the button for "send a private message " to appear in their public profile. 5.) I want the uploading of images to be super easy when worker is publishing his offer and the employer is publishing his project. After the images are attached I want them to immediately start uploading (the same as it is on odesk.com) They should be able to upload as many images as they like and they should be able to choose which image will be featured. The images that will be displayed on the offer/project are described in the picture "ponuda proizvod.jpeg". 6.) I want the search function (together with the search filters) to be integrated into the header. I want also the header to always follow you as you scroll the page up and down. Please check the pictures "upper-header-always-follows-you.jpeg", "napredno-proeki.jpeg", "napredno-ponuduvachi.jpeg" and "napredno-ponudi".
