Improving the way leveling works, which should take effect tonight.
Currently most good to excellent designers fall between level 6 and 10. Only 15 have broken level 10. Which makes levels 10 - 20 pretty useless. What the new system does is smooths the distribution of levels and you'll level up more often if you're posting good boxes (especially HoF level). All of the designers currently sandwiched between 5 and 10 will now be between 5 and 30 or so.
Some will drop in level, but most who are between 6 and 10 will jump up.
Note that there will probably be some tweaks over the next day or two, so don't be too surprised if you see levels fluctuate for a bit. Once things look good, then level-based achievements will be enabled.
