After a networking meeting, it's important to follow up with a thank you letter. Start out by thanking the individual with whom you met. State the specific advice and leads you were given. Say you will keep in touch and do keep in touch! Add the individual to your contact management system.
Follow up with your network every month with an update on your search, pass along an article or other piece of information the individual may find of interest, and a copy of your updated personal networking plan. Your plan includes a brief summary of your skills and accomplishments, and your targeted industries and companies.
