I've added your remote and tried to push to it directly. But I cannot force push to it, which I have to do for the rebasing. I think as long as it's only three people developing these features, it would be great if we can all have branches on the main repo, because I always end up taking these PRs, moving them onto the main repo and then pushing them.

@odeke-em fyi

Roger that @adrianbrink, thanks for the suggestion. I thought about that too when I saw that you had to copy a bunch of commits to a branch on the main repo.

[adrianbrink]

Do you have access to create branches on Ethermint?

[adrianbrink]

I'm closing this in favour of #298 . In the future please create branches directly on the main repo, because otherwise, we can't collaborate on features.

we can just check ^ that box on the right hand side but yeah, sure
