Hi.
There are more than one search options provided.
First, there is a box you can type in the terms labeled "search" at the right of the top header.
Right below this other two preset search options:
Hey username
Show unread posts since last visit.
Show new replies to your posts.
time and date
Should do the job quite well.
The other option to search for users posts is located at the users profile.
For an egosearch click on your username on the left and in the profile info section click on the "show posts" link.
Additional option is available under the "members" button at the top.
Can search for members there or browse the member list manually.
If you find the member proceed the search option in their profiles.
