Look for your your profile tab on the bar, than look for the signature tab.
In the signature tab copy and past this html code below in the siggy block:
[*url=http://fortheluvofart.blogspot.com/]FOR THE LUV OF ART BLOG[/url]
make sure to remove the star in the code of this html code (star must be removed for the link to work!)
change the http blog address to yours
Remove "FOR THE LUV OF ART BLOG" and edit it with ur Blog name.
Now make sure to head over to your profile tab again and look for preferences.
There are a bunch of questions.
Twords the bottom there is one that will ask you
"Do you want your siggy to show every time"
make sure to check yes!
Hope this helps and I will make it a sticky
