I Need A Little Help :)

Hey, guys!

So since I started to use the comment swap feature I've gotten a lot of well needed criticism for my stories. One of the biggest thing people have been pointing out is the fact that I need to double space everything. And after looking over my story again, I totally understand. I never really read it on Mibba to see that, but now that I have, I'm going to redo it.

My question is how can I double space my stuff, simply, without taking hours?

Now, I know how to double sace on Word, but whenever I copy and paste it on to Mibba the double space goes away. So then I actually have to manually double space everything, and it takes a long freaking time!

So if you have a little trick I should know about, then please let me know!

Thanks!
