Hi @Salesome
1. IIRC we have some QA checks already that check for missing parenthesis or numbers. There is probably a way to make them better, but I don't remember whether they are on a language or on a project basis.
2. I'm still looking at it from time to time, to fix some issues and to process language requests. @Gallaecio is still around, but he has really little time indeed.
3. There seem to be some statistics, https://transifex.github.io/openapi/index.html#tag/Activity-Reports/paths/~1team_activity_reports_async_downloads/post but I don't know if they make it more accessible than through code. Why do you want to kick people out? For reviewers I understand, but the others? Do you have some plan to build a close team?
4. The organisation is done by the extractor scripts, that parses a JSON file to know where to put the extracted strings. Recently the campaign project was added. More can be added I suppose although I would assume that might make the existing translations disappear.
5. GreatTower is a visible class, while Great Tower is the specific name, iirc we can't put spaces in visible class names. Maybe they shouldn't be translated. @Silier, @bb_ @Freagarach
