This is really a "no brainer", and doesn't even warrant a thread, where it can be endlessly beaten to death by the guard house lawyer types, who seem to delight in pontificating!
Having been there, and done that; I know that our FAI teams only real need is "money", as unlike a few of the foreign teams; our's are not fully funded, so just send a donation to whatever team fund you favor. In rare cases, where a team actually raises enough funding to cover all of their expenses; any surplus funds are retained for use by future teams in that particular catagory.
