English is my native language and I only speak English

Some of Huggle developers don't speak English natively and sometimes don't use correct wording or make mistakes in their English. Review the source English localization on GitHub: https://github.com/huggle/huggle3-qt-lx/blob/master/huggle/Localization/en.xml and try to identify issues, or fix them yourself and submit the patch. You should improve at least 2 items in XML file in order to be credited for this task.
