Add line between forums..
 

as you can see its kind of hard to see where the topics seperate: http://www.likenota.com/forums/ is there a way to put a horizontal line between each topic? or something similiar?..

What are you referring to as a topic? vBulletin doesn't use the term "topic".

the forums listed under what says discussion topic... for example

The office, The showroom, . .. . .. that stuff,\.

that is style specific you can change that in your main css options

ummm.. where? i dont see anything. but i dont want vertical lines i just want horizontal ones. and maybe have horizontal color changes..

You will need to add that code in your FORUMHOME template in the appropriate area. Not sure how you will go about doing it, you can use CSS with the following:

border-bottom:1px #fff solid;

That code needs to be applied to the table that surrounds your 'topics' as you put it.

You can always also insert an image, or use a <hr> tag aswell. Whatever you feel will give you a better result.
