"I advised you to dispose of your books, and advise it still. Be sure to do it, it will give you peace of mind.
But at the same time be careful not to become narrow-minded, or afraid of reading what is well written, quite the contrary, such writings are a source of comfort in life."
That is totally up to you. I more or less regularly take a look at my local region, as I know that my city often gets created in the wrong region, and then when I have free time I drop by this forum and see what I can help with. I leave more difficult and iffy stuff to those who are more experienced, and mostly handle simple merging of duplicate zones.
You are not obligated to do anything, you are just given the tools to help, and you can jump in whenever suits you best.
