Recently I started doing translation suggestions for co-maps, and I felt like this was a good way to contribute to OSS (since I don't have much money lying around).

Are there any other projects that you know of that want/require translations to Pt-Br?

No idea, but you could just go browsing for cool looking projects at flathub or some other repository.

It looks like Lemmy itself is not fully translated into your language yet:

I've come across a few projects that use Weblate or Crowdin for translations. In on of those two you can search for additional projects to translate without having to go trough projects repos. Last one I was checking was probably InkStitch or the ffmpeg webpage.

Damn, I had no idea.
Maybe firefox had auto-translated stuff before I switched the interface to english.

Pretty much all COSMIC desktop apps have translation support built in (because most of them are built from templates that support them). I'm sure many of them could use your help.

Hey I have one!

It happens to already have Brazilian Portuguese, but the translation is way out of date and is missing a lot I've added in the past couple months.

Bookmarked!

Cool, thanks!
