easy discuss module forum menu format

Hi,
I'm new to css and have been trying to make menu show horizontally (and i got to do that) but need to take out the dotted border around the menu and been trying to change background and menu font color.

menu in question:
Post Categories Conversation List Favorite Post Profile Edit Profile

would like to show menu just like above with no border/line. would also like to know how to change background color and font color. I'm probably accessing the class wrong?

created sufix ForumMenu1, and I tried codes below but they're not working.

div.ForumMenu1 {
background-color: #F0F0F0;
}

ul.nav.menu.ForumMenu1 li {
/* display:inline; this doesn't work*/
display:inline-block; /* this works fine , but not on IE -same with all..IE problem*/
list-style-type:none;
padding:0px;
background-color:#F0F0F0;
color: #C80000;
margin-bottom:-10px !important;
margin-left:0px !important;
border: 0px !important;
}

ul.nav.menu.ForumMenu1 li.item {
background-color:#F0F0F0;
color: #C80000;
}

Thanks.
