How to add "rel=me" to social links?

[jemostrom]

Some social sites uses a rel="me" tag to identify/link a user to a web site. For example Mastodon that suggests a link like this

<a rel="me" href="https://mastodon.social/@xxxxxxx">Mastodon</a>

Can I set up this in the config file?

No, you can only set the icon in the config file.
You will need to change the template code. But, this will apply the rel="me" to every social item.
