Here is one of the most important parts of Adding Signal; Signal is not only about being accurate and building reputation, but it is also about timeliness and adding signal as quickly as possible after the origional content was posted to the internet. Catching content within 5 mintues or even the first hour after which it was posted by the creator will earn bonus credits in the system.

You simply go the the creator's feed and click the "Catch Content" bookmarklet. it will import the content to your pop up browser. For content creators who are already in the system you must add at least one comment to the content you are catching, For a creator that is not yet in the system you need to add both a comment (Thought on Chain) and complete the Add Signal panel to add signal to at least one of the pieces of content you are importing.
