Did you ever get a great idea while you're driving? Or learn about an important event when your planner is nowhere in sight? Or try to juggle multiple tasks without the aid of a PDA? A new online service called BrainCast may be the solution you've been looking for.

Now in beta test, BrainCast lets users call an 800 number to record reminders over the phone, mobile or otherwise. The reminders are saved as audio files and delivered to the user's PC via either email or RSS feed.

BrainCast also offers an organizational system for managing messages online. You can tag audio files with descriptive words that facilitate sorting, and add notes to each message. You can also share recordings with friends, family and coworkers via email.
