@skorokithakis could you check this pull request?
If you prefer that I divide it in partial pull request, tell me and I will rework it.

[skorokithakis]

Oh sorry, yes, I was intimidated by the sheer size of this. If you could split it up, that would be great.

[FedeG]

Ok @skorokithakis, I'll split it and resend it in different pull requests.

Thanks for the response

[skorokithakis]

Thank you, but you've created them against your own repository, which means I can't merge them here.

[FedeG]

@skorokithakis All pull requests are independent, you can merge one by one (or merge one and not another).

Only the translation pull request (#148 and #149) use the code from #147, but they don't have a conflict or problem regarding the merge order.

[skorokithakis]

Wait a minute, this isn't one of my repos! Wow, how did I get involved here?

[FedeG]

@skorokithakis I don't know hahaha.
You responded to my pull request, and I understood you are a maintainer.

It's the official repository of https://pypi.org/project/django-webpush/

@safwanrahman Do you maintain this repository?
