launch site wordpress for viral campaign

[Admin]

For my project Emoscale, I was looking for myself a plugin for wordpress to create quickly a launch page, where I could put the email field and let people to be connected to my twitter and facebook ( or other social networks )

I used ET Anticipate from Elegant Themes, but i don't know why I couldn't enter a date

So I started to find alternative
