We recently moved the forum onto a brand new server after having issues with the previous provider. To help cover increasing costs of running the forum the subscription price has increased to £25/year.
However, if you are already a subscriber you will still pay the same amount you currently pay for the length of your membership. For the majority of members that will be either £10 or £15 depending on when you upgraded. You will only have to pay the increased fee if you let your membership lapse or cancel your PayPal subscription.
