I have concern that as the devs move on to new projects, keeping up with account support and abuse reports might start to falter. I'm not laying any blame or guilt about this, I understand the realities of business and the limitations of time.
If this is wrong, and the devs have no issue keeping up with support, then maybe just keep this offer in your back pocket for later if things change.
If this is right, please give someone(s) access to the support tools. This way the game can continue to be supported without depending directly on the devs to indefinitely spend time on a project that hasn't generated profit.
note: this is not a request for the source code or to be able to release fan made updates, as others have requested. I don't think that's a good idea. This is specifically asking that some trusted person(s) be given access only to what they need to respond to abuse reports and account problems, nothing more.
