There are two ways to submit content to the site. Here are the choices:

• Personal Blog Entry
  I'm imagining that this will be the most frequent choice. In a blog entry, you can document your thoughts, initiate a conversation, or post something interesting that you've found and think others might be interested in. Click on "create content" and then "blog entry" on the navigation menu. This will allow you to collect your content in one place that others can access. If blog posts are particularly interesting to the whole community, they can be promoted to the front page.

Also, if you're quoting from an article, just pick a paragraph or two that makes your point, and then include a link. Folks can go read the whole thing on the original site.

• Event
  You can let others know about an event by clicking on "create content" and then "event" on the navigation menu. Set the day and time with the menus, then add a description of the event in the text field.
  

You can also comment on other's posts by clicking on the title of a post and scrolling to the bottom of the page.
