I'm interested! I feel I've outgrown my current guild, since I'm now providing about 1/3 of the total gold and 1/4 of the seals. I'm looking for a more active guild with players who all donate what they can. Chat sounds cool too; I probably won't be super active but I'll pop in here and there.
Level 269, my usual donation is at least 200k gold, around 700 seals, around 100 trophies. I obviously get to rank 1 by midweek every week. Your "donate generously" thing is a little vague, but I feel I'm being generous for my level--pretty much all of my gold goes to guild tasks.
If that all sounds good to you, let me know and I'll leave the current guild and post my invite code.
