Okay so if you know NLP then you know that when communicating with someone 7% is what words you use, 38% is the tonality, then 55% is your body language.
So when you're emailing, texting, ect. you're only portraying 7% of your total game!? That blows right.
Well here's my own ideas and field tested theories to help it.

When you ask them a question such as: "Do you wanna hang out?" instead of the ? mark, replace it with a period. so it'll be: "Do you wanna hang out." Their concious mind will think "oh it was a typo"(if they even notice it conciously at all) while they're subconcious is processing it as a command. They'll be more apt to say yes.
And if you're feeling ballsy then go ahead and CAPS in embedded commands. "Do you WANT... TO HANG OUT." and that will just amp up the pressure to say yes.

Now is it possible to portray your tone and body language in text? No way, right?
WRONG.
If you say anything C&F or teasing put in =P it's a tounge sticking out it shows that you're being playful. And you can display other moods and such with other smile faces.
Smiles: :) :D =D =)
This is for devious or naughty >=)
This is a wink ;) or ;D



Hope this helps ya guys! =]

I like the idea of using a period instead of a question mark in a text, but using caps might make you seem belligerent or pushy, not to mention strange for using caps while texting.

that's why I said IF you're feeling ballsy.

Good post!

I've recently been texting this girl who i met, and I've been using emoticons to show that i'm playing around but I like the ? . thing , I'll test it out.

Clever, I like it!

Actually, I've used the period on a question before, but it was more in an angry context.

I have this crazy habit when I text someone I use "?!" at the end of the sentence... girls never complain about it and I always hear what I want... lol
