When uploading a new profile image using the default "My Profile" atom the image doesn't render until you click save - so unless you try clicking save to see what happens it appears that it hasn't uploaded

I want http://sewersandwatermains.ukwir.org/ to go to a tool in the UKWIR website

I want to upload some documents - including our current Terms and Conditions - and then link to them on some webpages. Should I make a document object or just upload a file? Whats the difference - whats the benefit of either?

I have some webpages on my website that I don't want everyone to be able to see, but myself (as admin) and my employees will work on them, if I Deny General Public permissions on them will that work? Is that the correct thing to do?

I am getting confused with the difference between something being URLable or Viewable as they sound like the same thing? What's the difference?

I want to have a webpage show in my main menu structure a few times in a few different places (Its a 'contact us' webpage), do I have to make the same webpage loads of times? Or is there a better way then duplicating it?

I want my website to look good and work well for both desktop and mobile users, so do I need to make a separate website for mobile users?

Currently if one of my users wants to change their details they have to request the change by email and then i change it for them. This takes up a lot of time so i was wondering if there is any way for them to do it themselves?

I have managed to make a template with all the relevant atoms but now i need to know how to add content and edit them. How do i do this? Do i need to access the back end or is there a way to do it on the front of the site?

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?
