Hi. I noticed you tagged an article that I edited which says that this article has "multiple issues." I am a little new to wikipedia, and I hope you can point out to me what changes I need to make in order to meet the standards of wikipedia to avoid the "close connection" tag, the "original research" tag, and the "notability" tag. Perhaps these tags don't have anything to do with my edits, but the edits that came before me? since the article was up since January, and I only made my first edits in March, can it be that the problems are from previous edits that came before mine? If that is the case, I am ready to change those edits too, in order to improve the article to meet wikipedia quality standards. I really appreciate your help. the article in question is:
