How to welcome neighbours

Lifehacker has a helpful post on the subject.

One of the more valuable things you can do for a new neighbor is to put together a cheat sheet for the neighborhood. Write down all the important stuff that a new person wouldn't immediately know about like what day the bulk trash pickup is, special events in the neighborhood (block-wide garage sales, social events, etc.), and other information specific to the neighborhood that a new person might find out about after the fact.
