Original Post
To add more value to our GDNet+ service without actually having to add any true new services, perhaps we could place an upload box(s) on the new topic/new reply page for premium members. When they click post it would save the file(s) to their webspace, and then append the text of their message to include a hyperlink to the file(s). While we wouldn't really be adding a new service, it would make using the webspace for hosting forum attachments a one step process, which I think our users would percieve as a very good value (in fact I think we could get a number of people to signup based on the fact that you could "attach" files to your post automatically, even though it was technically possible with GDNet+ before)
