If you're running something, it should be in the forefront of your mind and choosing to run something should mean that you're going to put it above other non-real life things and run it, whatever that means. If you're not willing to post to keep things moving, you've got the wrong group. If you're not willing to make necessary administrative moves to keep things moving, you should appoint someone to do so or not be the GM. If a GM can't do all their necessary tasks to keep the RP alive, they should make sure it can be done whether that means appointing someone to do the dirty work or creating a rule to just point at so you can virtually wash your hands of it, not take up the spot and leave an awkward position where the position of power to clear up problems refuses to exercise it. Otherwise any little road bump kills everything. In terms of bad memory, I wouldn't make/join more stuff than I can handle on my plate but that aside, you've been poked and prodded on top of the Iwaku alert system.
Of course, this is in the past but I would highly suggest considering this for anything you run in the future.
