At some point in the next hour or so, the forum will be temporarily unavailable while I upgrade to SMF 2.1.7.
This will only affect LemmingsForums.net; other sites on the server (such as NeoLemmix.com) will not be affected.
The upgrade is now complete. Please report any new issues that arise.
Attempting to use SMF's built in upgrade did not work. I thus proceeded with the usual method of branch / merge wizardry. But it occurred to me - it makes more sense to keep a branch of vanilla SMF in the repo, to make it quicker next time around. So that's what the "smf-vanilla" branch on the repo is for.
I've noticed the disappearance of a lot of forum avatars, including mine.
I suspect this is the issue. ;)
