When you first log in, the only option available is to configure the site. Once you have done this, the other options will appear.
In general, keep moving forward. This is because the pages are generated as you request them in order to ensure that they always contain the latest information. If, for example, you delete a page, and then go backwards through your page cache to a page that was created before the deletion, you are likely to end up editing or deleting the wrong page!
Carrelet produces static pages. This is generally a Good Thing, but it does mean that you need to specificially reload them when you make changes. The 'reload' button of your browser should do this. If not, try ctrl-reload, or turn off your page cache. Web site proxies may also cause problems in this respect.
Pages are only valid for about 30 minutes (this is to prevent someone else from calling up one of the pages from the browser cache at a later date and using it to change your site). If you spend more than 30 minutes on one page,Carrelet will refuse to accept the changes, and you will have to log in again. To avoid this, click on modify every ten minutes or so (this also effectively saves your work).
If you want to start a new paragraph in plain or formatted text mode, you need to leave a blank line.
