SUMMARY
There's a glitch in the _excellent_ Plasma 6.4 announcement web page https://kde.org/announcements/plasma/6/6.4.0/?source=plasma-welcome . At the end it says
> You can provide feedback direct to the developers
> via the [#Plasma Matrix channel](https://go.kde.org/matrix/#/%23plasma:kde.org)".
But I don't think there's a #plasma channel. Instead you're routed to plasma-dev, whose intro message says
> Users should discuss topics in #kde:kde.org or https://discuss.kde.org 
> Bugs should be reported using https://bugs.kde.org".


STEPS TO REPRODUCE
1. Visit https://kde.org/announcements/plasma/6/6.4.0/
2. Scroll down to "Feedback" section
3. Click the link  [#Plasma Matrix channel]

OBSERVED RESULT
You're routed to https://go.kde.org/matrix/#/%23plasma:kde.org , but this displays the welcome message for #plasma-dev:kde.org, which tells users to discuss topics elsewhere.

EXPECTED RESULT
Rephrase a little and guide users to #kde:kde.org , unless you want users to provide feedback direct to the developers in #plasma-dev in which case change the Matrix link to that.

ADDITIONAL INFORMATION
This feedback section is not in the markdown for the web page, https://invent.kde.org/websites/kde-org/-/blob/master/content/announcements/plasma/6/6.4.0.md 

But I found the phrase in https://invent.kde.org/websites/kde-org/-/blob/master/i18n/en.yaml#L201
