PULSE
Php User Login System Exentended
...The most frequently used features are already implemented into Pulse, so you can't help thinking about Machiavellian ways to realize your projects.
Even if Pulse is easy to use, it's strongly secure: it has on its side the power of MD5 and SHA-1 algorithms! Salted properly!
Pulse is fully opensource, you may download and re-distribute the code in any form, a link back to the project would be appreciated, but is not required. Enjoy!
