Whew! so i finally figured out how to do this. If you ever have a really long post, you can add a "page break", or what ever they're called, by adding this bit of code (without the quotation marks!) where you want the break to be:
<"!-- more --">
this will make your post an expandable summary with the full post viewable via link(s). Which will make the home page look a lot neater. I tried it on Paula's picture post and JM's lastest one. For some reason it gives two links but I'm too lazy to figure out how to fix it right now.
Again, exclude the quotation marks (they're just there so i can post the code without it creating a page break!)
Also, make sure you're in "Edit HTML" mode when you enter the code.
