To clear up any confusion, although the forum was changed from phpBB to vBulletin, your login (etc) has been imported into new tooling. So
you don't need a new account to continue using the forum.
If you encounter problems with your original account, please contact me.
The most likely reasons.
1. forgotten the userid and/or password
2. incorrect E-mail
3. E-mail filter
Together we'll figure it out soon enough, the worst sollution would be getting a new
password!!
