Looking good @zoek1! Is there a way to add UTM's to the "Join" buttons?

Also, It needs to say "Hackathons" in <h3> centered above so it is clear. I believe it was in the mockup.

@PixelantDesign @octavioamu this will replace the Disqus widget that has 2+ years of stale content on the gas history page. This page gets a lot of organic search traffic (see GAnalytics) and advertising our current hackathons seems like a better use of space.

@zoek1 could we make the code reusable ! I believe we have the exact same format on the hackathon list page
So ideally make that into it's own file and import it in both places

[thelostone-mc]

DRY code needed

[jdorfman]

@thelostone-mc will this allow @zoek1 to add custom UTM's so we know where the sign-ups are coming from?

[thelostone-mc]

@jdorfman So this would be mapped to the buttons + would be based on the URL from which the users click on them right ?
yeah that's possible even with DRY code

[thelostone-mc]

@jdorfman closing this out as this code is also present is open in PR https://github.com/gitcoinco/web/pull/7502/commits

[jdorfman]

Thanks @thelostone-mc !
