Some links in Rail Girls guides are broken

[shayanealcantara]

Description:

I was searching ways to know better the organization and unfortunately, some links in those topics were broken. So I think that it's time to make a doc update, because the project is so cool, and then people could enjoy better :)

An example in yellow:

Steps to get the behavior:

• Enter in Rail Girls Guide http://guides.railsgirls.com/;
• Click on How to organize a Rail Girls Event;
• Try to access links in the page, like: 'organizer's Slack discussions forum.

Expected behavior:

When someone clicks in a link, access its content.

The link works now.

Thanks for opening an issue about it!
