The latest version of SCMeta, the Meta data manager for Joomla sections & categories is here. Version 2.0 comes with many long sought fixes as given below.
Change log :
1. If no meta data is present the plugin would not show the default meta data
2. Section Meta keywords do not reflect in some cases
3. Category meta keywords do not reflect in some cases
Why wait for Joomla 1.6 when you can have a Section, Category level meta management in 1.5 ! Get it now ! ( Note that you need to be logged in to download)
