Re: Networking follow up...months later
There is no drawback to reestablish connections with people you have made contact with at conferences etc but you shouldn't wait too long. Make sure when you do so your spelling an punctuation is perfect in all correspondence. If you are trying to network with someone who is above you 2 or 3 rings on the ladder it is even better to mail a real thank you card with a specific reference to something you learned from them during your conversation.
Even better, if the person is within a reasonable travelling distance to you call or email them and offer/invite them out to lunch which you pay for of course. Since you are still in school see if there is a possibility to intern for them as well. Good Luck!
