Just curious... The yearly subscription would include all current and future xf2 add ons you would be developing? I am glad that you are finally monetizing your work and unified payment for all your add-ons is a great idea.
Yesterday, i was refreshing/removing some of the addons installed on my forum and yours were the only ones, which i could not even think of removing... Keeping them FREE is an icing on the cake... Thank you, Salute!
