I want to activate my Diamond Card
To activate your Diamond Club card simply enter the email address (if you are not logged in) you registered with and the membership number found on your Diamond Club card.
If you bought Diamond Club membership for yourself on KJ.TV by selecting the 'I want to join' option / your Diamond Club code on your card ends 'DP', here's where you can register your actual card number to activate your membership code so it can be used on the store for a 10% discount, and for future reference for certain Diamond Club benefits. This is not a requirement for simply accessing the Diamond Club areas of the site, as you will have setup your login email address (or confirmed to use your existing KJ.TV forum login email and password if you have already registered for the KJ.TV forum before purchasing the Diamond Club membership) when you purchased.
If you received Diamond Club membership as a gift or bought it from amazon.co.uk / your Diamond Club code on your card ends 'SP', you need to instead select the 'I want to activate my Diamond MEMBERSHIP' option (or navigate to http://kj.tv/diamondclub/activatemyaccount) to setup your whole Diamond Club account.
