[Zope] mysqlUserFOlder question

from teh mysqluserfolder docs: ". Also, it is not possible to create/delete roles. That needs to be done using sql client." So this means that i need to add a role to the database manually, rather than through the interface. OK. is this an arbitrarily named role, or is it the 'mysqlUser' role that the product says it knows about internally?? (BTW, the .sql file distributed with mysqlUserFolder is missing a field- the EMail field doesn't get created, and so the product doesn't work until you fix it- easily done by editing the script, dropping the database, and readding it.) can someone give me a brief pointer? i'm plugging mysqluserfolder into squishdot, if that helps :) elijah
