I second Izuki, there’s quite a few active Kaldorei guilds right now! I feel your pain about your schedule, I work full time second shift too.
I can only speak for Dor Serrar, our events are usually at around 8 pm server/central time on various days throughout the week. Because of my schedule, 99% of the events I personally run are on weekends. All our guildies are online at various times throughout the day and night as well. We have no uniforms, wear whatever your character wants to wear! Our forum post is here!
