You have to give it to some couples who really take time to record every bit of their preps - online! With the increasing wedding activity in the country, helpful tools have also become available to the present-day couples such as http://www.weddingannouncer.com/ or http://www.mywedding.com/ to help update guests and friends as to the level of the preparations being done.
Is this helpful? Yes, we think it is. It also adds to building the excitement leading to the event day itself. Cons: you have to take time to work on this so as to not make it look "bitin". It helps to be honest, too, about everything, frustrations included. Otherwise, we think it's a fun thing to do together as a couple-to-be. :-)
