The recent idea I had with allowing first and second perspective in a clear way was to prefix the paragraph's or sections of the story with the character's name, I mostly do sections when I swap perspective but I could see it working on paragraphs too.
Then I had that other story where I wrote the perspectives side by side but that requires special bbcodes to be written, I may be playing with that today actually just to enable me to put one of my already written stories with that over on this forum

right now it is in a html file, since it needs special tags. Yeah gonna look at that right now
Testing columns:
Cara:
as the sun sets I strip naked, I apply moon oil all over my body and hair and bring out my two swords and start my evening sword dance, the last rays of the sun caress me with their warmth as I make my blades heavier to really strain my muscles, as the sun sets I feel the star and moon light caress me and the cool evening winds caress my sweat glazed skin making me get goose bumps.
John:
I hear a woman straining and get curious and follow the sounds curiously, and peek from around a tree, I see a gorgeous naked oiled and glazed with sweat blonde elven woman with two elven long swords that she is dancing with, her scent is alluring, making my whole soul and body erupt with lust and hunger for her.
Tara:
You are sitting up in your hunting hide in the old oak tree and see a man watching Cara's usual sword dance, you can see him trembling and his huge erection is straining against his brown well worn leather pants, you have almost without thinking finished fletching your last arrow that you were making for the hunt you and Cara are going to go on tomorrow.
Mike:
lYou wonder where John went, he said he was just gonna take a leak, but he has been gone a long time for that, and the stew is almost ready to eat, it smells delicious.
