Confirmation email in the new versions for registration is good,
You should format for quick copy paste. Double-clicking on the code mid-sentence causes copy of (4782 ) the space behind it. I suggest format like...
Confirmation code: 4782
I noticed when I copied-pasted into this box with the space it did not input any info. After I went back to copy the code without the space, the "automatic submit" of the form worked. Neat!
Keep up the good work!
