Hi, welcome, Alex!
About the website link, you can try to insert this JS into your theme or a component:
Head
<script type="text/discourse-plugin" version="0.8">
api.modifyClass("controller:user", {
pluginId: 'enalbe-tl0-website-link',
linkWebsite: true
});
api.modifyClass("component:user-card-contents", {
pluginId: 'enalbe-tl0-website-link',
linkWebsite: true
});
</script>
About the Bio, I’m not sure how to do it yet. It’s handled in the backend (excerpt, stripping links).
