Ok, so if I had not made a posting and my account was removed permanently, does it mean I can sign up again under the same username?

cheers
 

Absolutely..

Now you will ask me - "what's the point of doing this at all"

1 - some of the emails bounced - so they were either fake accounts, or the member's email addy changed (?)
2 - at least two quality pinball people have posted since the email
3 - Several accounts had the same email address, as we had issues with the activation system the site uses (early days)

At no point in time were accounts going to be banned for not posting. From memory (Creech will confirm), there was a filter set to only have the emails sent out to accounts over the formation months of the site.
