In reply to Merlin:
> I would disagree, I think most are confusing the terms 'sponsorship' and 'donation'. The scale of the sponsorship should have nothing to do with it (football teams etc). As a sponsor you should get something in return beyond the satisfaction of just 'sponsoring'. The sponsored can also use what ever it is they plan to provide the sponsor as a lure to attracting further/more sponsorship - it's a transaction.
"sponsor" has more than one meaning and none of them necessarily imply that you will get something back in return, although that is very often the way it works. It basically means "vouch or pay for".
1. a person or group that provides funds for an activity, esp
a. a commercial organization that pays all or part of the cost of putting on a concert, sporting event, etc
b. a person who donates money to a charity when the person requesting the donation has performed a specified activity as part of an organized fund-raising effort
2. chiefly ( US ), ( Canadian ) a person or business firm that pays the costs of a radio or television programme in return for advertising time
3. a legislator who presents and supports a bill, motion, etc
4. Also called: godparent
a. an authorized witness who makes the required promises on behalf of a person to be baptized and thereafter assumes responsibility for his Christian upbringing
b. a person who presents a candidate for confirmation
5. chiefly ( US ) a person who undertakes responsibility for the actions, statements, obligations, etc, of another, as during a period of apprenticeship; guarantor
To your OP - I think you've got your priorities wrong. Surely the point should be the how much you value the cause the money is being raised for, not the suffering which your friend has to undergo.
