Adjust Posting Format

Ok, I just started here and I am trying to get things figured out. I am just dabbling with my site to try and figure out how I eventually want it to work.

the site is http://www.mmamust.com

I had screenshots for what I want the site to look like, edited in photoshop, but it looks like I cant post pictures on this forum, so I will try and explain.

Every time that I post something, it comes up on the site in the format
-“Posted on May 17, 2011 by klib0002”
-My comment would go here
-“Posted in Uncategorized | Leave a comment | Edit”

This can be seen by clicking on the link to my site. What I really want to do is make it so if I post 5 things in one day, it will all be under the same “date”. I put a screenshot on my site so you can get the picture of what I am trying to do. Being that my posts will theoretically only be a sentence or two, I dont want to waste space with all that other nonsense. As you can see by the screenshot as well, the comments will still be enabled, but the link to them will be in text format at the end of each post.

So pretty much, my question is, what do I have to do in order to get my posting format into that of the screenshot?

I am currently using 2010 Weaver 1.5.4

Thankyou
