Recently active topics in Triggit tagged with beta invite

I just created an account with the invite code "nisswa", which I found in this support forum, sent by one of the triggit representative.
It is working fine on one of my blog.

But I want to add triggit to another blog of mine.

Can I do it with the same account. If yes, how?
If no, can I create another account with the same invite code ? I tried creating another account for my second blog, with different email and the same invite code. I was able to do so, but when I inserted the java scrip code to my second blog, and tried to login, it refused my to get in, saying

Login Failed: Have you placed your Javascript on this site?

What do I do to have Triggit on my second blog?

Please Help.

I saw Zach demo this and it is a stunning app. Now I just need to get my hands on it. What do I have to do to get some?
