Yes. You'll have to use the "Tax" method, which has the option "Inactive Days Before Tax Applies", with the description "Use this option if you wish to apply a tax to users only if they go inactive from raiding for a minimum length. For example, enter 21 if you wish to tax the players who haven't raided in 21 days. If you leave this at 0, then everyone will be taxed."
This is the only method of decay that works with the inactive part.
Ok, I started using this and I see one issue. It is charging people who's alts have not raided. It should not charge people for alts not raiding when they have been 100% active on their mains.
Still having to go in every 7 days under adjustments and manually delete all the taxes placed on alts. Any idea if there is any light at the end of the tunnel for this one?
