While the original iterations weren't all that successful, I met a lot of good writers during 10thDoM's run, and made a lot of better friends. In that regard, 10thDoM was hugely successful and there are still a few people who appreciate it for what it was.
That stated, one thing that's stuck around from 10thDoM is the annual "River of Mnemosyne Challenge." The first three RoMs happened on the original 10thDoM site, the fourth RoM was pretty much the only thing that happened on the revived site, and the fifth RoM happened right here on good ol' Irreverent Irrelevance.
Why am I bringing all this up? Well, because the sixth RoM will happen right here on good ol' IrreX2, as well.
Yep. RoM6 will start on February 1, 2015.
You see, the friends I made at 10thDoM are all real-life friends now, they're pretty much all social-network friends, and I've met most in person and plan on meeting the rest very soon. And they all want to play.
So, if you're interested, take a gander at last year's rules here: 5th Annual "River of Mnemosyne" Challenge. There will probably be some minor changes to those rules, but those will give you the gist. The new rules will post February 1.
Hope to see you there. Or here. Or whatever.
