As heard on the latest Five(ish) Fangirls Podcast episode, May's photo challenge is The ABCs Of Science Fiction ( The ABCs Of SciFi for short).You should know all the rules ( though they are more like guidelines ;D) by now. Anything related to Science Fiction ( Tropes, Books, Movies, Shows, Games, Comics, Authors known for SciFi, etc) is fair play. Starting on Friday. May 1st, the hash tag to look for and use is #TheABCsOfSciFi.
If you do have any questions, don't be afraid to ask. Also, if you have any suggestions for future photo challenges, let me know.
