There are various ways to go to the profile of another member:

1. On the forums, simply click the name as it appears on the right of a post they have made.

2. On the news feed, click on the name left of a status or post they have made.

3. Go to "My Account". Then go to "My Friends" and "Find more people". You will then find a list of all members on the NOD website, and have the ability to search.
