I'm sure that you've seen talk about this on the forums, but I just wanted to make a news post making it official!
I'd like to have 2,000 users online at any point between now and November 15th. If we can make that happen, I will give every user who has logged in the past month a free Loyalty Pet Slot Totem which can be redeemed for a free pet slot! (Which means you can get another pet)
Also, if you're online when the 2,000 people are online you get a super cool achievement, an a forum title to go with it!
There are a few topics on the forums where users are trying to organize and make this happen.
Good luck!
For those saying a GA medal is required to redeem the extra pet slot: if my understanding is correct you don't have to buy a GA medal unless you're already exceeding the amount of pets you currently slated to own without one.
Using myself as an example: I have 12 pets right now. I've used 2 totems in the past to give myself pet slots, which means that when my account has GA status I have 12 pet slots. When my account doesn't have GA status, though, I have 7 pet slots, because the two totem pet slots aren't tied to the GA medal. If I'd never used a GA account to create 5 extra pets, I would have 7/7 pets, and using this pending (hopefully!) totem would put me at 7/8, allowing me to create a pet for the empty slot. However, because I've used a GA in the past to create 5 extra pets, I'll be at 12/8 and will require the GA medal to bump my available pet slot total to 13.
Anyway, my point is that I believe users who have never used a GA medal to create pet slots should be able to use this totem to make a new slot without requiring a GA medal. If I'm wrong on this someone please jump in and correct me.
