An IP address is a unique indentifier for an individual session on the internet. Sometimes this address changes when you disconnect and reconnect (usually with dialup connections).
If we have blocked your IP address there is always a very good reason. Typically users "spamming" the boards or being intentionally disruptive by creating multiple user names cause IP blocking. Sometimes this results in entire IP blocks being banned.
This could mean innocent users are being prohibited from using WHT. We apologise for this inconvenience. If you think your IP has been unfairly blocked, please submit a helpdesk ticket we will assist you in gaining access to the Community.
