BuddyPress.org

I plan on putting my own custom logos with links in the upper sidebar for a more customized feel. I am gonna put an icon and text description right below, and both will be links to their (blogs) backened (write posts, edit posts, etc…) blogs. How can I do this? I tried:
? php echo bp_loggedin_user_domain() ? post-new.php
but it didn’t work it wouldn’t add the username to the address bar. It kept redirecting to the dashboard, any ideas?
