Ran into a few more difficulties than expected, but ultimately, the upgrade was a success and we're now on SMF 2.0.15. Additionally, we now have automatic regular backups in place - prior to now, we've relied on myself or Nessy manually making backups, which neither of us have been particularly reliable at doing. That's changed now - it's all automated, backups will occur once per month. This will occur on the 1st of the month at around 6AM UTC; the forums and NeoLemmix.com may be slightly laggy around this time (probably for about 5 minutes at most). As has always been the case, the backups are accessible to all administrators and global moderators, and are hosted off-site.
As always when any updates to the site occur, please let us know if you encounter any issues.
