Thanks for your message. You're right, the name OObsart is very close to OBSART. Do we need to hide ourselves behind fake name to enhanced Wikipedia? OBSART is non-profit, why do you talk about promotion links? The link is just posted for information. Did you check the contents of landart.fr? It is a place entirely focusing on pioneer Land Art with historical documents, collaborations with artists like Robert Smithson, Nancy Holt, etc. I thought Wikipedia was free but it is not. You erase OBSART without real reasons, not because of wrong contents but just because of a name. It is not fair, and it is above all a pity for Wikipedia's users interested by Land Art.
