The new logo is "flat" compared to the 3d appearance of the cube, especially at the size of a 16x16 pixel icon.
Yes, I am as this is something I can do as stakeholder but who lacks dev skills. I must confess the sign-up process was a nightmare, but I think people are aware of this anyway.
For the record:
First activation email never received.
Second activation received, but embedded link sent me to main forum page instead of activation page
Confused from setp two I then tried to reset password, in case this was the problem, was told account existed but not activated
Repeated activation, followed link in email, back to main forum, remembered that the reset password page had a final box for activation code
Followed link to reset password and entered activation code, it failed
Next link in activation email stated if having problems follow second link and enter activation code provided.
Second link in activation email also dumped back at main forum page
Finally copied the link text from the second link of the email and pasted into browser, this time I'm directed to a page with a single box for activation code
Copied activation code from activation email and pasted into box in browser, voila I am activated and account enabled!
In conclusion I would suggest the embedded URLs are getting mangled in the email so when you click on them they are truncating and users are being directed to unintended locations
