Your account on the UCSB board is a "local" account--i.e. specific to that board. What you should do is try and register again (here or there) with a "global" account. If "jkline" is taken (which might have been why you went "local" in the first place) you'll have to try some variant..."jklineUCI" perhaps. After that you'll be able to log in to either UCSB board and this one with the single account. It will also lock up that username in case any other school jumps onto ezBoard in the future. In theory a global account should work on Insiders boards as well (BW Boards) but I can't get it to do so.

Post again if you're still having trouble!
