My work on this language version of Wikipedia is mostly limited to replacing image filenames that have been renamed on Commons. The changes are made with a script that uses my Username. Sometimes I replace filesnames without this script manually. In both cases, depending on your language version, you may need to review my changes first. If you can, please give me the autoreview rights. This would eliminate the need for the reviews to a minimum. Otherwise, it's fine.
If you have any questions to me, please write on my discussion page on the German Wikipedia or Commons, preferably in English, and I will be happy to answer your questions.
