We’ve received a few enquiries about registering on the site, so I’ll post the answer here in the hope of making things clearer.
The short answer is you only need an account to buy something from the shop, and you can create an account when you’re checking out (at which time you would be entering all of your details anyway).
You can make comments on posts just by leaving an email address – no account is required.
I hope you enjoy using the new site, and we’ll keep making tweaks to make it more usable for you as time goes on. If you have any more questions about any aspect of the site, ask me here.
