Oh, I have an idea that doesn't use any programs, depending on how computer savy your player base is.

Simply have guidelines for each player where when they make a new post. They would add a hyperlink to the post on their character sheet, which would be named after their character and the post number (like in your example) Then as often as you'd like you'd just have to click view raw, and paste over that portion of the post index. 

If you wish for a system where you have full control, or don't want to burden your players, there aren't a ton of options. Perhaps if you explained your problem with the programs a bit better, I might be of more help. "data" is a small word that can mean a lot of different things.
