Do you know how to create a portal?
If you do, then take, Date, MethodofCorr, Note and define date and text fields for them in a new table. Add a ContactID field so that you can link this table to your contacts table. (If you don't have a contactID serial number field in your contacts table, you need one)
Use Manage | Database | Relationships to link it to your existing contacts table and enable "allow creation of records via this relationship" for your new table.
Now you can place a portal to this new table on your contacts layout for recording notes on each communication from that contact. (Hint: you can make a portal row several lines of text tall instead of the default single line of text row height to better accomodate the needs of your notes field.)
