A few different questions; maybe a tad difficult.

[JABRONI]

1. I want my posts to be separated like the picture below where it is rounded at the bottom and top of each post by each individual member. Mine right now is kinda hard to make difference of each post.

2. Same picture, how do I make my user postbit like that one where it shows the messages without the popout?

3. Do I have to code a donation box by myself or is there some sort of plugin because I feel like I've seen this same donation box on a few different sites.

4. How do I show all my subforums like the picture below?

5. How do I edit the background of the forum?

Thanks to everyone who helps me here, I'm new to the Xenforo software :]

For 1 and 2, experiment with the Style Properties to achieve the look you want.





For 3 and 4, check the add-on releases and template modifications forums.
The donation module may be part of the portal add-on, the sub forum listing thread is here: http://xenforo.com/community/threads/tutorial-sub-forum-grid-listing.10978/

For 5, It's done in Style Properties, depending on which background you mean.
