Ok, I have a problem to solve...

I have a table of IT projects I've created for the IT Staff at a client site.  The UDT is called ITProjects, and the settings are as follows:

-- all users for this site are in the IT Staff role
-- all records are viewed by IT Staff role
-- users can manipulate only their own records
-- IT Staff role can add record and/or edit their own entries
-- display settings are Predefined: AdvancedTable

Here is my problem:

1. I'd like all IT Staff to be able to "Comment" on each project, i.e. add their own notes to a record that someone else has created.  But I don't want them to be able to edit anything else.  How do I accomplish this?  I was thinking of creating another UDT called Comments, and having a 1-to-many relationship between the two, with the ProjectID as the foreign key in the comments table.  Can this be done?

Thank you,
