Border around my big logo

http://gatheringofwatchers.com/

Is there a way to remove the thin grey line around my logo?

Yes it's in the general CSS of your theme.
You can find this sort of things faster, if you use Firefox + firebug plugin. 

I had to go check this out because I could not for the life of me recall a "gray line" around the logo on any Dolphin site in a base install.  Of course, I was surprised to see the question, so I looked and I saw a gray line around the promo code section of the index.php page  Well, golly be, I didn't think of that section at first....

Well to answer Faithful's question now, I guess I have to since I've been proven, in a way, that there is a gray line around the logo, if you load the logo into the promo field.

To help you out there Faithful, use Firefox with Firebug (it's a free add on and will break down any page you want very easily for you, showing file paths, line numbers and even allow you to edit pages on your screen without disturbing the server files until your ready)

To remove that pesky gray line (AKA Border) just do this:

Go to:

templates/tmpl_uni/css/index.css

Locate the following lines (it's located at line #62 in yours)

 .promo_code_wrapper
 {
  border:1px solid #ccc;
  margin-bottom:10px;
  padding:10px;
 }

Then alter it to look like this:

 .promo_code_wrapper
 {
  border:none;
  margin-bottom:10px;
  padding:10px;
 }

***Note, don't delete the line as it may decide to call another border then from the general.css files, just remove the 1px solid #ccc and replace it with the word none and that pesky gray line will go away.
