well, since members tab link is a matter of theme, if we hack the url, it will affect other tabs too(say activity/forums etc which i think you don’t want to redirect on main blog), so easy way will be to to edit the header.php and change the lines for member tab link in theme(forum does not allow here html so the link on pastebin).

here is a link to pastebin http://bpdev.pastebin.com/0EXgZ4Sf
