How to log in
First, make sure cookies are enabled in your browser.
Click on the Log in link at the top right of the page, or go to the log in page.
You will be prompted to enter your username and password. If you haven't logged in before, you will need to enter your password twice.
You may give your email address if you like. Other users will be able to send email to the address, but they won't be able to find out what the address is.
If you click the box Remember my password across sessions, you won't have to give your password again when you access the wiki from the same computer.
Click on the Preferences link at the top right of the page for various options, such as changing your password.
Your User page and Talk page
As a logged in user, you will be able to create your own user page and talk page. When you are logged in, you will see your username displayed at the top right of the page. Click on this to get to your user page, which you can edit in the same way as any wiki page.
Most users write a little bit about themselves and their interests on their user page.
You also have a talk page. You can access this by clicking on the Talk link next to your username at the top right of the page. Other people may write messages in your user talk page by editing it, and you can respond.
Log in problems
If you appear to be able to log in, but as soon as you try to look at a page after the "Log in successful" page you appear logged out again, it is very likely to be a cookie problem. If you are certain that cookies are enabled, make sure that you haven't inadvertently listed this site on a list of sites to never allow cookies for. (This feature is available in (at least) Mozilla Firebird (Firefox) 0.6 and above and Microsoft Internet Explorer version 6 and above). Also make sure your computer's date and time are set correctly; if they are not, cookies may expire before they're supposed to.
How to log out
You can log out any time by clicking on the Log out link at the top right of the page.
