Ways to increase sales on ecommerce sites and increase sign-ups on service sites,

Read it. Do it. Awesome advice from Tog.

clever signup/login ui

For one of my side projects, Leafy Chat, we have just added the concept of user accounts. This includes the need for registration and log in (as well as log out and forgot password and so on). Leafy Chat only requires an email address and a password for both registration and log in, so it would be great to have some clever way to have both forms on the homepage.

Designing login/signup for a web server

Very smart. Stealing this idea for a current project

Interesting thoughts, but I don't like the end result. People have been trained over the years on how to do login/signup. Putting them both on the same page seems like the right idea, but there's something wrong with this implementation--it looks different from most forms.

"So after probably far too much research, I've come up with the following single register/log in form for Leafy Chat. Log in Sign up The form updates via JavaScript when the user selects a radio button. For the log in form, notice that the submit button says "Log in" and there is a link to retrieve a forgotten password. For the sign up form, the label for the password field prompts the user to "Choose a password" and "Sign up!" while also accepting the terms of service. I like this design because a user can either log in or sign up directly from the homepage and the radio buttons stand out and make the options clear to the user. I love that the page dynamically updates to provide relevant help for the chosen form. Also, the user can easily correct any errors without re-entering their email/password. What do you think?

Build a Login and Registration System with XML - NETTUTS

Building an entire membership system can be a tedious, and time-consuming task. Tim Cooper is going to show us how to build the ENTIRE thing in roughly thirty minutes. Rather than using MYSQL as our database, Tim will instead demonstrate an alternate approach: using an XML file. We'll be reviewing PHP, .htaccess files, sessions, and more!

button Design

Sites with user registration want to grab every visitor who goes their website. They list their website in every popular search engine, use advertising in other websites, work with bloggers to help promote their products, enlist the help of usability experts and go through great lengths to get noticed.
