Allow Longer Admin Email Recipient Field
By default, the ContactBuddy "Recipient Email Address" field allows up to 45 characters of data. This means you can enter in one or more than one comma-separated email addresses, as long as they all fit within the 45 character limit of that field. This can be changed to your needs.
In admin.php file, inside contactbuddy/classes folder, on line 293, change the "45" values (listed twice) to the exact numeric value that you would like.
That will change the length of the Recipient Email Address field in the ContactBuddy admin panel, allowing you to enter longer or more than one comma-separated email addresses.
