How to insure sortition would be attractive to most?

These two articles about the salaries, or lack thereof, offered to state legislators make me wonder about two aspects of any prospective sortitioned legislature.

The first is the question of how to attract and sustain participation, particularly regarding financial support.

The second, consequentially, is whether or not citizens should be required to actively submit their names to the pool for sortition. [“Not required” would be, then, as juries are chosen. “Required” would require registration…and possibly, further, a basic competence test — a la driver’s licences.]

Granted, both topics have been previously discussed in this blog. But I recall there is no agreement about either.
