hmm - I guess this might be a bit troubling to some people here but it appears to me that for some of us it is a matter of having as many loans as possible - and such in need of shortest possible loan terms.
Let me try to advocate the longer term loans and their attractiveness to me as a Kiva lender; often it is people with little financial strength, aka need more time to pay which equals to be indeed helping the less fortunate of us.
Most countries I do not know sufficiently but if Ukraine is an example to go by they have plenty of middle class people receiving loans here - the record I have seen is 12 times the average salary of a Ukraine teacher. Yes you get your money back in 2 months but over time I for one have come to the conclusion that there are worthier loans available here.
If you want to reloan often I suggest stick to the 25 dollar and make as many as you can but longer terms as 1 loan of 100 dollars on 2 months is equal to 6 loans over 1 year while 4 on 25 dollars over 12 months makes 4 - I think that is not so bad

Anyway - a feeble attempt to advocate that it is much to be gained for oneself looking to the cause itself. So please look to the people behind the loans I say
