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
