Highrise, the popular web-based contact and correspondence app from 37signals, has a new dedicated Tags tab in the dashboard. This will help users filter and sift through their contacts and notes much more quickly, especially since the company built in the slick ability to select multiple tags with which to filter. Clicking one tag in the cloud begins the process, while clicking another will switch to filtering by just that tag. After clicking a tag, however, the upper right of the tag cloud (pictured) will offer a 'Multiple tags' option. Once clicked, each subsequent tag you select will add to the filter, not replace it. This is a very smart way to offer the best of both worlds for everyone, no matter how they work and use tags to sort their correspondence.

Earlier this month, 37signals added a One Bar feature to allow users of their Basecamp project management and Highrise correspondence tracking services to sign into both sites at once. Fortunately, after issuing a major update to Backpack, their wildly popular web-based PIM app, they have added Backpack to the One Bar signin. This will save some time and simplify switching between these services, and the only requirement of One Bar is an OpenID, an increasingly adopted service that allows you to tie website logins to one single ID and password for the ultimate in web security and convenience.

If you're a fan of 37signals productivity tools, as the DLS crew is, you may appreciate a newly added feature from the clever kids with the funny name.

Basecamp and Highrise now offer a single sign-on that allows you to eliminate one of those constantly open tabs we all live with, saving you precious RAM and system resources that can be put to better use. If they'd only add Campfire to the single sign-on party, we'd be ecstatic.

Highrise is an online contact manager built by the famous 37 signals, founders of the ever popular Basecamp project management tool. It was quietly launched yesterday to the public.

Highrise tracks leads, clients and vendors, allowing users to stay on the ball with who gets spoken to, when, and about what. This allows for members of a team to easily decipher the next plans of action. Notes, calls, and tasks can each have reminders set to them for easily remembering to follow up. When signing up for Highrise, each user will get a unique email address, when items are sent to this email, they will automatically become tasks, taking the extra steps out of lining up items to be completed. HIghrise is at its most effective when an entire company works with this online tool. Employees can share vendor, clients, lead, and co-worker information to see what has been previously communicated, and what was acted upon.

Rates vary with Highrise. There is a free plan with 2 users and space for 25 contacts which is great to try out the software and see if it could fit in with your current operation. Then users can choose to upgrade to a basic plan that allows for 400MB of file storage and 5000 contacts for $24/month. If that isn't enough, $149/month can get you unlimited users, 20GB of storage, and up to 50,000 users.

Highrise is a great compliment to the other online software packages that 37 signals offers, as data is communicated effortlessly between all of them.
