There are a lot of installed modules such as blog, forum and banner....etc under modules definition.
However, I do not see their links to use it, e.g. no forum and blog links in home page.
Do I need to add new modules in control panel as I saw there is a drop down list of those installed modules.
But, I do not know what do they mean: Insert Top / Bottom, Visibility Same as Page / Pages Editor only, Align left, center, right.
What does Install Additional Modules mean? What does Add Existing Module mean?
When should use Module Definition Validator ?
