<p>When using people as reference, it's common sense to let them know. But what if you didn't keep in touch with them for more than two years? If you contact them all of a sudden only to let them know you're using them as a reference, then they may think you're just taking advantage of them, calling them only when you need them. You may look like a selfish person.
What are some ways of keeping in touch with people you want to use as reference for the future? Would it be good to send them regular emails to ask them about how everything is going?
Thanks.</p>
<p>Yeah, it would probably be good to send them emails, call them, etc. just to keep up with what's going on in their life so it doesn't seem too unexpected when you tell them you're going to use them as a reference.</p>
