Many of us have been in the situation where someone has done some web-design work for us for free and then wandered off our social graph. You either don't have time to change the site, or you don't know enough HTML to pull it off. Your donated website ends up languishing somewhere, unloved, un-updated, un-hit.
Typeroom may provide the answer for you. Typeroom is a web-based site design tool, but with a twist. It allows you to do web design with its layout tools, as do many other companies in this space. But Typeroom allows you to enter a specific web site which it then copies to its own servers for editing. Once on their servers you can edit the site with their WYSIWIG editing tools. You can take that old, donated site and spruce it up to your heart's content.
Once you've made your edits Typeroom can reload the finished product back to your own server. Check out the video for a better explanation.
Right now Typeroom is in closed Beta, but if I can wrangle an invite I'll let you know. I have a languishing website that badly needs editing.
