We all know forum signatures are a relic of the past, but there are still a lot of communities that really love them. Since Discourse is I crafted a plugin that lets us take back our much loved (gif animated) signatures!
You need to enable the plugins options for all users by going to your Admin settings over at your-site/admin/site_settings/ and navigate to the plugins section your-site/admin/site_settings/category/plugins. Then in the filter box, type in signatures to filter out this plugins settings:
You can also enable advanced mode on the plugin settings and use a full-blown post editor to create your signature! With text, multiple images, etc.
Thanks to @charleswalter who pushed for this and made it possible, @eviltrout who made it compatible, and the Discourse team for such an amazing project.
Notes:
It is not possible to make this default on for all users; users must intentionally opt in to have a signature experience.
Enable advanced mode if you want both pictures and text in signatures.
Hosted by us? This plugin is available on our Enterprise plans
Unfortunately people in one of the forums I run are complaining about signatures, too. “This is a thing from the 90s, also many signatures are too heavy and even if not they distract too much from the content of the threads.” In this forum, it’s 50/50. Interesting. We were already thinking about putting the content of the signatures in the “About me” box of the users and turning off signatures for this forum.
Personally I like signatures, also in the year 2024. But it seems not everybody thinking that way.
Anway, because of this reason I want to ask for a feature request:
Can you introduce a switch in the user profile/settings to turn off signatures? And maybe also a global switch to set a default (on or off).
