This accounts belongs to User:MGA73 and it is a bot. It is only active on some wikis.
It works on the pywikipedia framework and is mainly used to all sorts of work related to files. It is manually assisted and runs whenever I feel like doing something.
The bot has a good friend User:MGA73bot2.
So if you have anything to say please contact me at my talk page on the relevant wiki --> User talk:MGA73.
