For a few weeks, I've been using it for myself and improved it. The most tricky part was getting familiar with UN jargon: for instance, what's the meaning of each contract name. Is it consulting? Is it for foreigners? What's the experience required?
I also had to add all the agencies, offices, and departments.
SEO is not bad, people are coming and start to register already. Now I will start to create promotion tools for Twitter and Reddit, to automate a bit the marketing side and get more traffic.
