The main thing to remember when editing content, is that WebGUI creates a "version tag" that keeps track of all your edits (its default name is your username and current date).  To publish your changes so that everyone can see them, you need to "commit" your version tag.

To edit content you need to be in "admin" mode (click the "admin" link on top right hand corner of page - the Voxforge admin needs to give you account permission for this to appear).  A new admin menu appears on the left hand side of your web page. 

To commit content click the "Version Tags" category in the admin menu, select "commit my version" - if you click this, then the content you edited will become visible to everyone.  No content changes are visible until you commit the version tag!

If you log out and log back in without committing the changes you've made, then you changes will not be displayed, and the things you edited will be locked (the padlock icon appears).  You need to select the version tag that you created in your previous session to make it active.  To do this, click the "Version Tags" category in the admin menu, and click your version tag.  

If you don't select your previous version tag, then WebGUI will automatically create a new version tag... this can get confusing, because your previous edits will still be "locked" under your old version tag.

The commit process is useful because you can edit multiple web pages (even on different days) under a single version tag, and publish them all at once with a single commit. 

WebGUI has a tutorial (WebGUI-Primer.pdf) and also a sandbox (http://demo.plainblack.com).   Look up Page Layouts, Articles, Forums and Shortcuts.

Some Concepts/Definitions:

A "Page Layout" is container object.  Think of it as a directory or folder that displays its contents as a web page.  The way I've got things set up, this is where you can change the menu name from English to your language.

"Articles" are objects that contain your text.  You can have more than one article (or any other object) on the same Page Layout.  Just click edit on the article menu, and overwrite the text with the translation of the corresponding English page. 

"Forum" is an object... which, if you are reading this you would obviously know, lets users submit posts and post replies.

"Shortcuts" are pointers to other objects that are displayed on the Page Layout they are located in. Usually this points to another article or forum from the English side of the VoxForge website.  You cannot change the object that the Shortcut points to, but you can "overwrite" some of its properties.  Using this feature you can overwrite the title (i.e. translate it to another language) of the object being pointed to.

Putting it all together:

Therefore, if an Article and a Shortcut to a Forum (or any other object) are contained on a Page Layout, when you click the URL of the Page Layout, the content of the Article and the Shortcut will be displayed, in the same way images are displayed on a web page, even though the Article and the Shortcut are both uniquely addressable through their own URL.
