Mixing the registration fee with the fundraising goal sets a poor statement as registration fees are meant to cover more administrative and planning costs - where as the fundraising is supposed to go directly to the mission.  Mixing the two looks poorly on the organization and causes confusion for donors and participants.  

This is helpful when you enter in the discount feature.  As the current functionality is, if I have a registration type that is a $100 fee and a minimum fundraising goal of $500 - if I want to offer a 100% registration fee discount - the system looks as reg fee and fundraising minimum as "one" and not seperate.  So whatever the discount % is - it is applied across the total of the two.  IE:  it sees this as $600 - and applies the discount against that.  So if we want to apply a 100% discount - it removes both the registration fee and the fundraising minimum when all we want to do is discount the registration fee of $100.  So simple math says - just apply a 20% discount.  The problem there is that the registration fee is now $75 and the fundraising minimum $320.
