The contest has actually been over for so close to a year that VLDC11 is going to happen in half the time it's been since VLDCX ended.
So yeah, you can just submit your level for VLDC11 early next year because this is way too late. Although I recommend making the level within the contest time because it's kind of butt to get around that just because it's obvious what the restrictions are (even if we do plan to change some stuff around).
-------------------- Your layout has been removed.
For future reference, you can find out on your own if you can still submit an entry to a contest or not by looking if the Rules and Submissions thread is closed (has an "OFF" to the left). If it's closed, then the deadline has already been reached.
