You can! Creddle can import some of your information from your LinkedIn profile if you sign up with your LinkedIn account. A few users reported a 500 error on importing which I'm looking into now, so let me know if you also have trouble.
Missed that. You should expose the signup options on the main page (unless you already have and I missed it). I would have signed up if it was simply a matter of clicking to connect creddle to LinkedIn.
I think that would be better too, that's my fault for hiding it behind that extra page. I'll look into bringing those up to the front. Thanks for bringing it to my attention!
