Hi everyone,
Would really appreciate if someone can advise on your experience: its a rather silly dilemma but we have 145 guests and i have no clue how to even start collecting everyone's mailing address. In today's world i realize I am one of those people who always use e-mail and i barely remember my grandparents address (please don't judge) 
Any hints or tips/tricks on how to ask people for their info? Where can i store these addresses (excel? database websites?) I would really appreciate your help!!!
Thank you!
