Plugin translations

Hi! I’m developer of plugin and I also provided language files (.po and .mo) for czech translation. Now, when theres Glotpress (web translations) I want to use it to let people translate, but I also want to import my Czech translation into it. Is there any simple step to import the translation?

I also tried translating my readme.txt with the app, but I can only “suggest” translation. Is there way to let plugin’s author correct and accept the translations?
I want to correct and accept all translations myself, becouse WP Developers (or whoever is in charge of accepting translations) aren’t interested in having my plugin translated (especially to czech) and it’s only waste of time
