All you have to do is go to this link and it will tell you where to go from there...http://twitter.com/badges. That's where I went. Good luck and welcome to Twitter too!!! XOXO
Go to www.twitter.com/account/settings, and there's a link underneath the "More Info URL:" that says: (You can also add Twitter to your site here) -- click the link, click the Blogger icon, click Continue, and then you have two options: 1) If you're familiar w/ Blogger layout, there's a link to the code (go into Layout, click Add a Gadget, pick HTML/Java Script, paste the code into the box, save it and voila! 2) Not familiar w/ Layouts, click on the Blogger button you see there. Hope this helps -- it's pretty quick and easy :)
I am absolutely no help here but I do commend you on joining Twitter. I am completely lost when it comes to that!
http://twitter.com/account/settings go to that site and if you click right under more URL settings it will say you can add your twitter to your website. Super simple and it's the official twitter html and all that shiz. good luck!!
