Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Alphasights Technical Challenge

Using Ruby on Rails we would like you to create a simple expert search tool. The application should fulfill the requirements below. The source code must be placed in a public repo on GitHub. The application should be deployable on Heroku.

I enter a name and a personal website address and a member is created.
When a member is created, all the heading (h1-h3) values are pulled in from the website to that members profile.
The website url is shortened (e.g. using http://goo.gl)
After the member has been added, I can define their friendships with other existing members. Friendships are bi-directional i.e. If Sasha is a friend of Ash, Ash is always a friend of Sasha as well.
