Some info for you: it says “DIYnot Test” because it is exactly that - a test. It is not currently available to purchase, and the wording has not been finalised.
Over the years we have had a number of requests from members asking whether there could be a paid no-adverts version of the site. We are exploring whether this might be a useful optional feature for people who prefer not to see adverts but would still like to support the running costs of DIYnot.
To be clear, the forum is not becoming subscription-only. Logged-in members already see significantly fewer adverts than non-logged-in visitors, and that will remain the case. This would simply be an extra optional choice for anyone who wants it.
It appeared before we had intended to mention it publicly, hence the rather unhelpful test label.
