The polls for CSM 13 election will close at 12:00 UTC on June 11, which is 24 hours from when this post goes live.
If you wish to vote you do not have much time left. Instructions on how to vote are available in a CCP news post.
I listed out the candidates in a post when the elections opened up, but if you want deeper details there is the CSM Wire site. However, you have one less choice at this point as Creecher Virpio has been removed as a candidate by CCP.
CCP Guard also did a Reddit AMA about the CSM and the election if you want more details and can stomach a trip to Reddit.
