wewe sort of can. wewe can either use the new ukuta on your profaili page to 'update your status', au wewe can use the area for text underneath your jina la mtumiaji (on your profaili page). To put text there, just go to your profaili page, click on 'Edit profile', go to section 2 (Fun stuff about you) and update your status in the section called 'My Motto'. Click submit and your new motto/status will appear in your profaili page.
wewe can also update your status in the meebo bar (at the bottom of wewe page), when wewe click on 'live updates'. So plenty of options!
