I am a Wikipedian from Sweden, who has some interest in Interlingua, but currently only knows it a passive level from various Romance language studies at adult education. I could also be found with the same username on English and Swedish Wikipedia. and English Wiktionary.
Sorry for writing so much in English, but my Interlingua knowledge is limited and I can't express myself well in it at the meantime.
If I am to make mistakes creeping in from Spanish or English interference, sloppy thinking or something, feel free to correct them, and leave me a message on my talk page for recurring errors.
