Just create a free Dropbox account, use that one to sign up for Harp, and then share the Harp site folder with your main account. It's a nice way to ensure that Harp is sandboxed.
This is a good idea. I probably don't even have to link it to my machine? But wondering what I'd loose out on for ease of updating. Will try this later.
Yeah you don't even have to link it. Just sign up, then link it via the Harp site, then share it using the web interface.
You don't lose out on anything at all, I'm doing this very thing.
