Hi All,
We are service based company, now start working on ruby on rails technologies. We need a CMS system with Blog, Events, News, Web Pages, Video/Podcasts, Emails and possibilities to send sms to multiple people together/selected options.
We need to develop this in within 5 days time frame with no experience
ruby team 
(We have one team member knew rails).
Can you recommend flexible, light weight cms systems please?
Any help is appreciated and thanked.
thanks a lot,
Krish
