Questions

How do you get a signature in the global forum?

You have to klick on user control panel (up in the right corner)
Then you can access your profile. There you can find a button with several options like Edit Profile and Edit signature.

Took me a few minutes to find it 😁

Thanks!

Did you find it?

No it's probably not for my device, I found the bottom you told me about but nothing about a Sig

Which device do you use?

Kindle fire.

Here's a screenshot from me. Thats how it looks like on my iphone. Hope it might be useful

If an ally alliance caught me supporting another ally and he knows it then what should I say to him?

That ur screwed. Lol. If one of ours supported a NAP or Ally against another ally, they would be reset by us or the other. Not good to support against friendlies.
