        <description>The Homebrew Website Club is a regular meeting for enthusiasts and hobbyist programmers who are building, or thinking of building, their personal websites. The meeting is an informal setting where you can talk with others,get inspiration, or quietly work on your site.
&lt;br&gt;&lt;br&gt;However, for the magic month of Hacktoberfest, Homebrew Website Club Nottingham is having a Hacktoberfest takeover!

Such a great idea to add rss for the events! Do you know what url the feed is available on? I've looked on the deploy preview and can't find it

https://deploy-preview-81--webuiltthisforhacktoberfest.netlify.com/

(the deploy preview link is under the merge 'checks' section on the PR)

The feed is here: https://deploy-preview-81--webuiltthisforhacktoberfest.netlify.com/feeds/events.rss

But it does seem to be missing data! Will take a look

[Codesleuth]

Ah right, it needed the other PRs merging. Let me update and it should contain data.

I want to highlight that the GUIDs aren't ideal - integrations will get confused if we add multiple events sharing the same GUID. I'm not sure what solution we can apply to this aside from manually generating GUIDs in the data and print those.
