Not only was I able to successfully register as a user named "spike2" in the CG Photo Gallery, but I uploaded an image just to be sure I could.
You can visit your Chasingame Personal Photo Gallery here:
Here is the image I uploaded as a test into your gallery: (just to prove it is working)
Now, Spike2, if you would like to "login" as yourself using the user "spike2" and the password I supplied, please email me and I will tell you what your password is.
I cant explain your problem but it may be a PEBCAK style issue, but I am not really sure. Let me know via email. I am sorry you had this trouble.
After you send me an email I will reply with your password. Then you can login and upload your own images, just follow the instructions Roscoe placed in the sticky. AFter you are in you need to change your email address as I used a bogus one.
If you have trouble from this point on, just let me know and I can delete the spike2 account off the gallery and you can try one of the alternatives that may be more suitable for you.
