@BryghtShadow Unfortunately Special:Chat doesn't support server side logging, although it's probably been requested dozens of times in the past. There is, or at least was, a list of features that might be added to chat, I think logging was on there.

User-logging is done in lots of wiki's chats and hundreds or irc channels. Whilst there are flaws with the logging bot going offline, it's the best that's currently available.
