I just browsed the SOL contest rules and #1 is:
1. All Characters in stories submitted for contests who engage in sexual activity must be 18 or older at all times when sex occurres (no sex during flashbacks to earlier ages). No underaged sex
The minimum age on SOL is 14. On Bookapy it is 16. Why is it 18 for SOL contests?
(btw, there's a typo in that sentence. "occurres" should be "occurs.")
