Subject: Show what user you're logged in as.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=fabd787a423f4b64bddfb43a57264e8aaa63ed44;p=mastodonochrome.git

Show what user you're logged in as.

Useful when testing two dummy accounts on a dev server, but might come
in useful for real people maintaining more than one config directory
as well.
