If you're not well-established on here socially, then PM me and provide me your name and a link to your Facebook profile (I may require that you accept a Facebook friend request from me). You'll be put on a "list", and if you stop posting for a long time then I'll check out your Facebook profile to see if you're still alive. If I observe by looking at your profile that you've died, then I will notify the DART community. If you stop posting but you appear to still be alive then from time to time I'll go back and check. Because I'm just some guy on the internet doing this, it may be the case that there's some delay in between when you die and when I find out about this and notify the DDO community. Also, you can be pretty much guaranteed no matter who you are that if your death occurs more than, say, 5-10 years from now then I won't bother to check for this, much less notify anyone.
If you've made virtually zero effort to participate here in any meaningful way (for example, your total count is 10 posts) then I'll be especially likely not to follow through on my obligations here towards you. But maybe. Who knows.
All such information disclosed to me in confidence will remain confident. If the Admin has a problem with this idea then he's free to just shut it down now and delete this thread. Otherwise, think of this as insurance of sorts that should you just suddenly die this fact won't go completely unnoticed by the DART community. I say "DART" community but this extends to whatever website this general bloc of people might one day migrate to, such as perhaps back to DDO or to some third party site.
