First,let me explain why some posts have suddenly disappeared. They were made by someone who initially appeared to want to help, but was in fact mainly concerned with promoting his own blog. It's something that happens often, and we don't tolerate it.

You've asked two questions as far as I can see.

First, you want to know if you can store your files in the Cloud for free, and the answer to that is yes. The best way forward for you is to use a free service called DropBox. It's used by huge numbers of individuals and businesses, and it works perfectly - I use it to work with clients for whom I'm developing websites. Take a look at dropBox by clicking here

Your second question was about site hosting. Your domain name isn't a problem - you can either transfer it to your new host, or point your site to its existing location from the new hosting space. What you have to do is find that new host, and I would forget about hosting in the cloud. Do it with a reputable hosting company, you'll get access to all kinds of helpful stuff like free website templates and software, and although you'll have to pay, the charges are very reasonable, considering you have a guarantee that your site will always be visible on the internet - no more of the unreliability that you're experiencing now.

My personal choice as far as hosts are concerned is Heart Internet. I've used the company for a number of years, and I like their professional, efficient service. You'll pay around £2:50 a month for your hosting package, but that's not a lot for peace of mind and the additional features you get.
