Question for Flailsnails Gamers/GM's

Has there been any established method of transportation, between game universes? Like, a side dungeon level, or spooky wood, that's a known "gateway to far-out places?"

If I were to run a Google+ Hangout Flailsnails game and you were interested in playing, what times/days would be preferable? Tuesdays & Wednesdays look fairly open on the CC Calendar.
