It depends ultimately you like the job scope a not. Does 'increasing' by 200 makes you like the work more? CC, RC, NC, volunteers, bosses, subordinates, citizens, suppliers, contractors etc all contacting you, almost everyday....

And when you officially join, you are considered a 'public' figure already. A lot of people will recognize you in the zone. A 'lousy' example: Maybe you cannot be seen drinking, parking illegally, cannot anyhow make comments online or anywhere etc......all these things will be magnified a lot more compared to 'non-public' people.

And are you married? have gf?

A lot of factors you must consider. Only you can make the judgement.....

and why the last CM quit like that?
