Heather we only have one forum on the DIS at the moment to cover Disney Wedding and Honeymoons.
So if we have a large number of bride to be's updating their Planning Journals on a regular basis then this will make it difficult for members to "weed" through those journals before they find new posts or answers to questions that they have posted.
This may be something that we look to do in the future, however something that I do note from a lot of Brides on this forum is that they are aware of how "public" it is and most brides are not comfortable with sharing all their information in a Planning Journal, when they know that a) their vendors, b) their guests, c) any member of the public and d) Disney Fairytale Weddings themselves can read everything that they post about their wedding and this can be a bit alarming.
From my own personal opinion when I started a Planning Journal I wanted it to be some place where I could write everything that I was planning and feeling without worrying about WHO may be reading.
Obviously this is something that we are monitoring for the future.
