To completely remove an Article, select the Articles that you want to delete and move them to the Trash. Next, open the Article Trash in the Content Menu and select the Articles you want to delete. After deleting an Article, it is no longer available as it has been deleted from the database and it is not possible to undo this operation.

A lot of different languages are available for the Back-end, but by default this language may not be installed. If you want a translated Back-end, get your language pack and install it using the Extension Installer. After this, go to the Extensions Menu, select Language Manager and make your language the default one. Your Back-end will be translated immediately.

Users who have access rights to the Back-end may choose the language they prefer in their Personal Details parameters. This is of also true for the Front-end language.

A good place to find where to download your languages and localised versions of Joomla! is Translations for Joomla! on JED.

Mambots have been renamed as Plugins.

Mambots were introduced in Mambo and offered possibilities to add plug-in logic to your site mainly for the purpose of manipulating content. In Joomla! 1.5, Plugins will now have much broader capabilities than Mambots. Plugins are able to extend functionality at the framework layer as well.

The improved Installer can be found under the Extensions Menu. With versions prior to Joomla! 1.5 you needed to select a specific Extension type when you wanted to install it and use the Installer associated with it, with Joomla! 1.5 you just select the Extension you want to upload, and click on install. The Installer will do all the hard work for you.

You indeed can change the Menu Item's Type to whatever you want, even after they have been created.

If, for instance, you want to change the Blog Section of a Menu link, go to the Control Panel->Menus Menu->[menuname]->Menu Item Manager and edit the Menu Item. Select the Change Type button and choose the new style of Menu Item Type from the available list. Thereafter, alter the Details and Parameters to reconfigure the display for the new selection as you require it.

Yes! Prior to Joomla! 1.5, only the text values of an Article and only for ISO-8859-1 encoding was allowed in the PDF rendition. With the new PDF library in place, the complete Article including images is rendered and applied to the PDF. The PDF generator also handles the UTF-8 texts and can handle any character sets from any language. The appropriate fonts must be installed but this is done automatically during a language pack installation.

Most Articles will be assigned to a Section and Category. In many cases, you might not know where you want it to appear so put the Article in the Uncategorized Section/Category. The Articles marked as Uncategorized are handled as static content.

In Joomla! versions prior to 1.5 there were separate processes for creating a Static Content Item and normal Content Items. The processes have been combined now and whilst both content types are still around they are renamed as Articles for Content Items and Uncategorized Articles for Static Content Items.

If you want to create a static item, create a new Article in the same way as for standard content and rather than relating this to a particular Section and Category just select Uncategorized as the option in the Section and Category drop down lists.

Well you are reading it right now! This depends on what you want to achieve. If you are new to Joomla! and have no clue how it all fits together, just install the sample data. If you don't like the English sample data because you - for instance - speak Chinese, then leave it out.

Within the Installer you will find a wide collection of languages. The installer currently supports the following languages: Arabic, Bulgarian, Bengali, Czech, Danish, German, Greek, English, Spanish, Finnish, French, Hebrew, Devanagari(India), Croatian(Croatia), Magyar (Hungary), Italian, Malay, Norwegian bokmal, Dutch, Portuguese(Brasil), Portugues(Portugal), Romanian, Russian, Serbian, Svenska, Thai and more are being added all the time.
By default the English language is installed for the Back and Front-ends. You can download additional language files from the Joomla!Extensions Directory.
