I have used a few download managers in Joomla, such as DocMan and jDownload. But my lastest favour is Phoca Download. First of all, that is a GPL component and Joomla 1.5 native. Moreover, so far, that is very stable application. I have not found any bugs at all. In addition, that is only a component. It has plug-ins and modules. According to their documentation, they has some plug-ins can add the links to a file, category and section to an article. I have tried their module menu. That is very good. It can draw a menu to all sections in my homepage, that is good for the user browsing the by sections.
Previously, I believed chaning menu title is in Menus->Menu Manager and edit the menu -> title. That is only for display at administration side. To change the display name in front page, you go to Extensions-> Module Manager. Each menu is related to a module, for example, there is a Main Menu module. So, you need to edit the module for changing the title.
Not long ago, a security release of WordPress has been pushed to the user. There are a new one today at http://wordpress.org/development/2009/08/2-8-4-security-release/.
WordPress 2.8.3 is released. They said this is a security release for 2.8.1. So, I think everyone should download that.

Moreover, I read an article at WordPress.org. 2.9 will come very soon.
