hi
You can run as many sites as will fit in the 55MB space allocated.
For uploading I would recommend an FTP application, I tend to use the FireFTP extention for Firefox, or FileZilla, both are free. You can do it using your browser, but it can be a bit 'fiddly'.
I'm not sure what you mean by 'manage separately'?
- you would have the sites installed in their own folders off the 'root' of your main address
e.g.
homepage.ntlworld.com/user.name/site1
homepage.ntlworld.com/user.name/site2
with an index.htm file in each with the main site code.
You could have an index file in the 'root' offering a choice of link, or just navigate to the appropriate site, directly.
- but Halcyon types faster than me
