The changes in Backpack make it nothing short of phenomenal. I've been using the past week or so, largely as a result of your previous posts about using it for GTD. It rocks my world. And here I'd always thought it was a scaled-down version of Basecamp. Two things to note: The Messages feature is available only for "Basic" and above, not for "Home" or for "Solo" packages; text entry in Backpack is still run through Textile (just like in Basecamp) so making links, e.g. in an actions list, is as simple as "Action text":http://example.com/actionpage This is handy both for external resources and also when you have a gazillion project pages. For larger projects, I create a project page, copy the URL to clipboard, then add the project to my projects list as a link to the page.
