I signed up with my Facebook account, but, when asked to enter my Pinterest username, it doesn't work!
I try to enter my actual username (alebegoli, which is working as you can see at http://www.pinterest.com/alebegoli), but Pinreach keeps aswering "you must enter a valid Pinterest username".
What can I do?

I cannot sign up because it says my pinterest username is invalid and I assure you it is not.

I have gone from 43 to 34pr score in one day ! as all my likes and repins data has been lost

I am using the correct user name Sweetness6645 and it wont accept it.

Not working when I try to regsister with my name. It said it does not exist but it obvioulsy does. Also when I try to register through Twitter it did not work

It's fucking annoying that it's asked me 3 times what my username on Pinterest is. Firstly, I typed the correct name of my Pinterest page and it still is giving me an error, secondly this is fucking annoying and is a roadblock to using your site (that I'm not even sure what your site does) but I'm not even able to get in to find out. That's a fucking problem.

my pinteret account is f7z but doesn't work here... what a shame...

https://pinterest.com/cheryloahuhomes/ is my address, yet I can't open an account using it as your site says cheryloahuhomes is an invalid Pinterest name. Huh?

It's trying to tell me that rae_bot is not a valid username on Pinterest when it's exactly my Pinterest username, and it works fine on PinPuff! I tried signing in with Twitter instead, but OAuth seems to be having a problem with a redirect loop :-/

It wont take my user name actioninpanama

after authenticating, I cannot access the service because the form says that my pinterest name does not exist. But I'm sura about what I typed

I've tried through twitter and fb and I haven't been able to sign up at all. Please help!!!!

Have tried everything
small case, with Capitals, with space between first and last name.
At least I do have pinterest

I have been trying to sign up for pinreach, but it keeps telling me that I have an incorrect username, which I definitely don't. I am so disappointed with this very obvious and inconvenient glitch, and I definitely would not pay to use a service like this.

Says: mysubletcircle is not a valid username when I try to register, but I know it is valid.

WIll not take my username. http://pinterest.com/custombikeshows/

I copied my pinterest username from pinterest, but pinreach keeps telling me it's not a valid user name.....

I am trying to register and am actually copying and pasting my username from the pinterest url - it is definitely the right one.
