yep, i am click reddit and +5 ARP, quest completed, thank you
Simply click the little facebook/twitter/reddit icons below this post, or any other you see anywhere on the forums, and you should get your ~5 ARP after a refresh.
Should grant you the ARP without necessarily sharing, but simply clicking one of the actions to attempt to share and start the process for those who do not have any desire to share whatever it is they're attempting to share after pressing one of the aforementioned icons. Hope it helps some of you who are confused and haven't seen this before!
NOTE: I've been told that this process doesn't work for everyone... for whatever reason. At least 90+% probably do get ARP from a refresh after closing a shared or not shared post.
