An amazingly good acronym and a perfect fit for high reputation, trust and integrity which relates to a dot-org name ending, with many excellent uses including its previous use as a Commodity Futures University educational site or involving money-matters and on credit unions.
We have owned this great domain since year-2002. CFU is a very popular acronym in numerous categories what with an extremely high 18-million results for "CFU' when doing a Google search.
CFU is on-sale due to owner retiring soon. In fact, a desire for retirement income is a reason owner can take a monthly payment plan (and a buyer's benefit).
P.S. No worries about using the domain while paying. You will have full use of CFU (the same use as you would have if you paid purchase price up-front) and use your own DNS immediately upon making your first payment.
