I've upgraded the serialsblog to Movable Type 4.x but am still trying to figure out how to add links. If you are interested in adding a new entry you can go to this link:
and log into UThink. serialsblog should appear in the list under 'My Blogs', click on that and then either click on 'Write Entry' at the top left of the page or run your mouse over 'Create' to get the drop down menu and select 'Entry'.
Check with me if you have any questions.
