TOPIC: separate checkbox list with break instead of comma in emails

Some of my checkbox items are long and when the list is emailed using commas to separate them, I get this mess:

Your details:
Course # 2 – The OCT in Retina and Glaucoma ($17), Course # 3 – Retinal Disease Update: New Treatments & Dx of AMD & Retinal Vascular Disease ($17), Friday Lunch with Keynote Speaker Tom Sullivan (No at the door registrations for this lunch.) ($25), Course # 4 – Procedures in Lid Lesion Removal for the O.D. ($34), Course # 5 – Sinus Disease ($17), Course # 6 – Utilization of Injections in Eye Care ($34) Course 6 runs at same time as Courses 7 & 8. You may only choose one., Course # 9 – Staff Management for Optometrists ($34) Course 9 runs at same time as Courses 10 & 11. You may only choose one., Course # 12 – Diabetes and the Eye: What we must know ($34), Course # 13 – CPR Certification (includes certification fee) ($75), Course # 14 – In the Pipeline… What’s New and What Works for Dry Eyes ($34), Friday Exhibit Hall Reception, Saturday Exhibit Walking Lunch ($45 each): 3 Extras

If they were separated by line breaks instead, they would look like this:

Your details:
Course # 2 – The OCT in Retina and Glaucoma ($17)
Course # 3 – Retinal Disease Update: New Treatments & Dx of AMD ($17)
Course # 4 – Procedures in Lid Lesion Removal for the O.D. ($34)
Course # 5 – Sinus Disease ($17)
Course # 6 – Utilization of Injections in Eye Care ($34)
Course # 9 – Staff Management for Optometrists ($34)
Course # 12 – Diabetes and the Eye: What we must know ($34)
Course # 13 – CPR Certification (includes certification fee) ($75)
Course # 14 – In the Pipeline… What’s New and What Works for Dry Eyes ($34)
Friday Exhibit Hall Reception, Saturday Exhibit Walking Lunch ($45 each)

Much easier to read. maybe give the user a choice in the Field area of comma or break separations for each field. That'd be cool.

where would I find to do this in the view files?
