i want space between my blog messages

Best,

when i write a blog message. i want some more space between the paragraph. but when i put my space bar, there is coming a new write block. so then the space is there, but when i save my message there is no space, because i did't write in the writeblock.

so how can i fix this space problem, without typing words.

thanks already.

( if it is not clear enough, please send me a message. my english is not the best hehe:)
