[otrs] Subject size/length

Hi all, Instead of trying to educate all of my users, I'd like to increase the size of the "Subject" field in the OTRS interface. Meaning: I'd like to make sure that no matter how the ticket is created, I'm able to see the full subject in the agent/customer interface. I think I found some articles for earlier version describing how to create a new theme, I think, to allow for larger subject lengths. I'm guessing I'm missing an option somewhere. Can anyone point me in the right direction? Thanks. -- /Sune T.
