So, the site is really helpful. The timeline list thing is a great guideline. The free wedding website thing is helpful and sometimes they have some good advice. Some people have said that you can't delete anything and I've not had this problem. Our wedding date changed and it changed ok, but I've not gotten married yet so I've not needed to take anything down.
That being said, I would avoid the forums. It's like any forum. A lot of people there want to be jerks.
Weddings are different from culture to culture and family to family (couple to couple of course). Therefore, something that is acceptable or expected in one culture is frowned on in another. People on this site don't know that and will jump down your throat if they disagree. If you need advice, talk to actual humans.
