Break up 'join us' user journeys from publiccode.net to about.publiccode.net/contributing

Problem this tries to solve

'Join us' is the first link on the publiccode.net homepage. It's above the fold, and looks compelling. It takes people to about.publiccode.net, with no clear way back to the more accessible or marketing content on publiccode.net, and very few contextual clues that users have clicked away from a website designed for the general public into one that assumes a much greater level of interest and contextual knowledge.

At the moment, about.publiccode.net/contributing acts as a triaging page for different potential stakeholders:

• individuals
• public orgs
• institutions and philanthropy

Based on the current audience prioritization in the product requirements document (#169), the latter 2 audiences are currently more important to us than individuals. The contributing page directs the latter 2 to email us directly.

The contributing guide for individuals (https://about.publiccode.net/contributor-guides/for-individuals.html) is the closest to a conventional contributing guide (which publiccode.net doesn't have - see #171), but does not include any reassurance as to how we handle contributions, preferred formats, etc.

Proposed solution

Short term: move About contributing page content to new publiccode.net contributing file (#171), so people are still on the same subdomain. Add more links back to existing general content.

Medium term: add specific user journeys/content for public orgs, institutions and philanthropy to publiccode.net with their own calls to action. Redirect these users from the contributing page to content aimed at them.

Longer term: remove join us link completely from home page, in line with @angelplasma's wireframes.
