Ive got a VPS using webmin. I have no idea what to do, I look at it and I have no idea what to do. How do I host my domain and how do I upload files?
Have you looked at Webmin's Documentation? Check out the FAQ and the eBooks. I wish I could be of more help, but I'm not too experienced with Webmin, pm me if you want more assistance.
you can easily get directadmin control panel for your VPS for as low as $6/month to make things easy...contact your VPS provider.
There is a usermin control panel for uploading files and folders. You need to use usermin to control the user based systems. and webmin for control and maintaining your Server.
