I need to let people log into my site but im not sure how to add in a login area. Could you please give me a step by step guide to adding a log in feature?

To add a log in feature set the atom you want to be a log in atom. This will then bring up a menu of settings for you to configure including page redirects, watermarks and remember me features. Once all these have been configured to your satisfaction click save and close and your login section should appear. If you need any further help just let us know.
