A blog is, in essence, an authoritative voice in the community. A blogger (or team of bloggers) distributes information in a blog post to an audience who's involved with the post subject matter.
Blogs are best suited to providing announcements, news, experience accounts or expert opinions on the subject of the blog.
How is a blog different from a forum, gallery, or wiki?
The format you use in Telligent Community depends upon your aim. A blog is about distributing focused information. The only exchange with readers is in the comment section, and the comments are not considered as important as the blog post. A blog is most appropriate when you want to talk about experience, news, or information from a point of view. In a forum, both Q&A and discussion posts can be allowed, and the respondents are as important as this the askers. In a wiki, you are recording information in articles for people to reference. In a gallery, you're providing files to view or download.
How do I create a blog?
Blogs are created in the desired group or subgroup using the pencil icon to access the Manage > Manage Applications contextual panel. Here, you can create each type of application.
