When I was in Behe/FNP/KoJ, we always had a section of the forums for those times when you had to go "Well shit, exams are next week and my marks are down, skipping WoE this week to study," or "Birthday, heading out with friends to drink the night away!" or even "Guys, I am throwing up all over the place, no way I can stay up to WoE today. The drugs are making me sleeeeeeeepy."
As long as you put in the effort to try and show up, level your character, and gear for WoE; most guilds won't even be bothered by the occasional week missed due to real life circumstances.
@Adrillf:
That sounds like fun actually, strike teams to attack every castle while a small force stays back to defend.
Might as well throw in WoE SE as well so the guild can leave 1 person behind to watch the Guardian Stones while the rest go raiding.
