Hello I'm a wikipedian very happy to join the most interesting platform where one can contribute and learn a lot. I feel like I landed on a place where internet is really internet.
I'm working on biography of saints specially in translating them to amharic and also creating new pages. One last of my many work is "ንጉሥ ካሌብ ጻድቅ (King Kaleb)" I hope I will stay long to contribute and learn more...
Wikipedia uses the Ogg Vorbis, FLAC and WAV formats for audio, as they are not encumbered by patents (an issue that prompted the decision that MP3 files will not be hosted at Wikipedia). Software supporting Vorbis exists for many platforms...
Various online tools (such as Zamzar) are available which let you freely convert one file format into another, and can be useful when you want to upload a file to Wikipedia.
