You mean I could have a
vacation from this ever growing pile of sMerit that keeps coming back no matter how hard I try to spend them?

What a problem and one many would prefer to have instead of the common one ''You have 0 sendable merit (sMerit) which you can send to other people.'' lol.
My idea here comes from all that applications in the past , and maybe we can see something like we have on the Default Trust 1 List.
So it could coosen at some kind of pool and change ever 3 Month.
Why 3 months, why not 1 like the DT system and after immediately you lose your merit source status, you lose all the source smerit. This will discourage hoarding of smerit but for this to be flawless, it can't be influence by voting like with the DT system. Theymos has to be the one deciding who gets to be the source or not. Now how does he choose the right candidates?. He can't ask for recommendations either because then we begin to have some favouritism.
