Easy question: Staffrank - sql query

[Ala21]

Hello,

i installed the staff rank hack, though it looks like it is limiting the characters allowed in the field so this is a problem if I am using html code and want to format the text.
I am not a SQL expert but I think it's because of this query:

ALTER TABLE user ADD (
staffrank varchar(100) not null default ''
)


How do I edit it to increase the maximum characters allowed? IF it's that limiting the characters, but i'd guess so.

Thank you
