BuddyPress

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?

Check out the bp_adminbar_blogs_menu() function in /bp-core/bp-core-adminbar.php for hints.

Depending on your needs, you could also use the blogs loop:

not sure how to use (bp_adminbar_blogs_menu() function in /bp-core/bp-core-adminbar.php) it. I tried this:
a href=”‘ . $site_url . ‘wp-admin/post-new.php”‘ . __( ‘New Post’, ‘buddypress’ ) . ‘/a
but it showed this in my address bar:

http://mysite.com/%27%20.%20$site_url%20.%20%27wp-admin/post-new.php

It didn’t show the user address. What part am I missing? Thanks
