Considering buying Eco Lifestyle - I have a few questions for players who have it

I have the pack and am very happy with it.

1. Pollution can be turned of in the settings. You won't see the score of the neighbourhood at all
2. NAP voting can be disabled. This doesn't disable NAP themselves but prevents any NPC from voting. In other words only votes you actively make as a player count. So you can still vote if you want and implement a NAP. Any existing NAP will remain active until you revoke them with the mail box.
3. Every week you will get a message that a NAP has been voted, even if you have voting off. This is a false alarm. With NAP voting disabled (and no votes from active sims) no NAP will become active despite the messages. I once had smog despite pollution being disabled. I managed to sort it out but it was an annoying glitch. But this was only once in all these years.

If you don't want to use NAP at all, I suggest disabling voting right away. I read about hidden traits getting added to sims with NAP which can stick around if you disable NAP's. Nor sure if this bug is fixed by now.

The neighbourhoods are very trashy by default. There are two special NAP's to change the neighbourhoods in evergreen harbour to make them look better. These are the only NAP's I use. They can be added with cheats by shift clicking on the mailbox/voting boards.
