Custom Post .color Per Usergroup

[Lynne]

You'd need to modify the postbit/postbit_legacy template and add in the poster's usergroupid as a class... maybe this line:
<li class="postbitlegacy postbitim postcontainer old usergroup{vb:raw post.usergroupid}" id="post_2377">

Then, in additional.css, just add some css to change the text color based on that.

.usergroup1 .postcontent {color: red;}
