Every one can contribute towards it in a meaningful manner, but it seems you are trying to create a monopoly of yours over all the articles, which is absolutely wrong. Do something more than, mentioning about Wikipedia policies. And remember Wikipedia is not peer reviewed so understand that there is always a scope of improvement and one should be open to it. And more than this, be more humble and please remember you are not the sole Editor of it, so give opportunities to other people to contribute (rather criticising everybody).
