local about = [[About:
I have started to make this addon as a tool for myself. Few people started to use it when I pushed it to Curse. Then updated it once with 6.2 release.
After some time I have catched a dialog on my own realm discussing it. I went to check curse page and I was shocked - it was in top-60 monthly downloaded addons with lots of suggestions and few bug reports.
I wasn't going to support it - because it was working - but now it looks like I have to spend at least some time to make it better.

Realm hopping has become a thing. The idea was rather obvious, but less people were using it at the start of WOD. Now every raid group with autoaccept are going to have some quiet people joining and leaving it. But since we became a huge community, it is up to us to control this.
The idea is to create groups from realmhoppers to realmhoppers. Taking small steps to not flood LFG too much. There are some ideas how to make realmhopping more comfortably while reducing annoyance to others.

FAQ:
Q: I cannot loot timeless coins / some other loot
A: Some items cannot be looted while in a raid group. However, rare timeless items can be.".

Q: I'm on the oceanic region and I can't hop to another realm
A: Unfortunately, oceanic realms are separated by Blizzard. There is little I can do :(
