Thanks. I love guessing correctly. There are so many possible pieces to consider.
First, are you dissatisfied with the current level of engagement? Perhaps a better way to put it is, is there actually a problem that needs to be solved? I am the type of person that loves procedures and guidelines. For ME, I'd much rather have something concrete in place than a loosey-goosey system but MY personal preferences wouldn't necessarily be what is best for the community.
Then, and I'm just covering my bases here, have y'all tossed around any other possible ideas or does a time commitment seem to make so much sense that y'all have stopped looking. Not necessarily wrong, just bringing up something to consider.
Next, assuming that there is an issue that needs attention, what type of commitment would you put into place if you were not going to take the here and there folks into account? Maybe they're already close to meeting those levels.
