I was busy lately, but as there is less than a handful of days til next month, and realizing there's no post here about it or i might not have seen it yet, let it be known that October is celebrated as Inktober.
The event was started by Jake Parker last 2009, as a personal challenge. However, nowadays it is a worldwide-- personal, still-- event for anyone to be part of. The main rules state that artworks should be of ink-medium, and there must be one work posted a day in accordance to the prompt.
But admittedly, you can modify the challenge for yourself, so long as you exercise your creativity for October.
So, main link and see for yourself: http://inktober.com/
