Once I define this we will make an announcement. It's not a critical function, so it will be in future development, not part of core automation. Most likely it would be 'when months inactive = n, where n is any whole number, then rshares_taxed = rshares * (n / 100)'

So basically at one month inactive, 1% of rshares are lost. At two months, 2% are lost, etc. until 100 months when rshares after the tax would be 0 and the member would be deleted. Eight years seems really like though. I will have to think about this more.
