Creating a blog in Weceem requires just two steps:
If you are using the default styling, when you create the Blog you can set the Template to the default blog template supplied.
Blogs in Weceem are just like any other content, and by gluing together a Template, some Widgets and some Weceem GSP tags, you get full blog functionality (caveat: pinging blog aggregators is not yet supported). See the examples in the default space template for further details.
To enable comments on your blog you must edit your Weceem security policy file and allow unauthenticated users to create content of type org.weceem.content.WcmComment [See how - link here]. Make sure that you do this for only that type, or malicious users may be able to create non-Comment content on your site!
The default space template for blogs uses widgets to render a single blog entry view, or a list of the most recent posts, and widgets to render the comment form and list of current comments.
The generic content submission mechanism of Weceem is used to submit comments by users, and the comment widget uses the Weceem content submission tags to set this up.
The Weceem archive tags are used to render the months for which there exist child nodes of type "Comment", with links to view those. Finally, the widgets render the list of tags assigned to the blog entry, with links to search for other blog entries based on those tags.
