# Joint Entrance Examination/2000 Screening/Q036 electrochemical cells simple question on potentials

 Welcome to the Highschool Help Forum! The forum is currently in "Beta" stage of development. You can ask questions and answer/discuss them. The basic functionalities are present. What's required is a more aesthetic look to the Static pages and a more user friendly setup. This will happen over the time gradually as we start creating some content. The site has a lot of tools, like posting mathematical calculations, images and diagrams; categorizing questions and so on. Having them here is NO GOOD unless you know how to use them. I am thoroughly against compiling a list of these features and then writing about them. As soon as you do not understand how to do something or use a certain feature, report that on "How To"s Section of the forum. Your queries will be answered there. If you have any ideas/discussion regarding the site/comments, please go to Discussions regarding Highschool Help Forum Lastly, thanks for joining in the site's development process! It matters!
