Jill,
I just want to give you a

right now!

Here are my thoughts on your positions:
ad 1) Mark Agwonah Memorial Fund
This is what I tried to do...if you look at the lender page name "
http://www.kiva.org/lender/markagwonahmemoria3530" you'll see that I tried. BUT: The Number of letters is limited to 27, so I had to change that to simply saying Mark Agwonah Fund...I would have liked the memorial in, too.
ad 2) Time for using the funds
We have a pretty full pocket right now, 425 $ if I saw correctly. I think we can invest in quite some businesses now (because, as you are rightly pointing out, the time to act is NOW and I hate to see the money sitting in the account while people need it), but stretching it out a little has its charms, too, because we will be able to pick businesses that are really in a way connected to Mark. Again, balance is the key.
ad 3) Long-term loans
I stated what I think of those. I really like your idea of large size loans, so that more people will see Mark on the lender section. We should definitely check that out!
ad 4) I sure would hope that Mark's mother will get a chance to see what is happening to her son's memory.
