You should create a network of wordPress sites.

during the process you have to add some code in your .htaccess files.
		
	 
	
	
	
 
		
			
	
	
		
		 @ejang Thanks for your reply but not sure how it relates to title not displaying correctly.
For example if I go to:
members; the title is Test Site | Members
groups; the title is Test Site | Groups
But if I go to a custom link called:
example; the title is Test Site | test post
testing; the title is Test Site | another test post
Anyone else with this problem?  Already filed trac and just want to confirm if this is a bug.
		
	 
	
	
	
 
		
			
	
	
		
		BuddyPress 1.2.5x hasn’t really been built with the WordPress 3.0 menu system in mind. I know we’ve got some page title bugs on a WordPress network/WPMU install which I hope to get time to fix in a couple of weeks so this might clear up then.
