Do I plan their Engagement Party?

First of all - does everyone need an Engagement Party? If they want one - am I supposed to plan that with the best man or does the couple themselves plan it?
I need your input!

If the wedding is in November 2010...

What should I be doing right now to help the bride? She has the date, the church and reception locations set...where do I come in for her?

Calling all Maid of Honor Guru's!!

Ok, so I am going to be the maid of honor for my best friend who just got engaged. This is my first time being in this position, and not just a "bridesmaid" - I want to make this journey the most memorable and exciting journey of her life - full of amazing memories and fun activities along the way. I am looking for great, simple and cost effective ideas (I am on a budget but don't want it to look like obviously) to make this the best experience of her life!
So I need your help - tips, advice, ideas, suggestions or other websites to check out.

Thanks in advance all you Maid of Honor Guru's!

Sincerely,
Amy
