Your website is not letting me pay; is it broken? If the website is broken, then we will already know about it and be rectifying it with our providers. Please ensure that you have registered an account on the website here and that you have selected all the correct options (i.e. membership type, any add-ons/donations) and entered all of the require information before contacting us. If this does not work, then you might prefer to send the (re)joining form to our London Office instead of using the website.
