As you have just started editing, I hope you find the following selection of links helpful and that they provide you with some ideas for how to get the best out of Wikipedia.
I notice you are making a lot of changes at Emirates Telecommunications Corporation. Unfortunately it is likely that your changes will need to be reverted because the text is not suitable for an encyclopedic article at Wikipedia. One problem is that there do not appear to be any references in the new material (all material must be verifiable and original research is not permitted). A more important problem is that the language is far too promotional: this is not the company website and text like "the long-term strategy of building a customer base ... paid off", and "customers are offered a wide scope of training and development services", and a lot more, is not suitable here. All articles need to use neutral language. Johnuniq (talk) 09:10, 3 October 2010 (UTC)[reply]
I agree with Johnuniq's concerns. From a google search, it appears you've copied the text from another website, which in addition, could raise copyright or plagiarism concerns. PhilKnight (talk) 09:14, 3 October 2010 (UTC)[reply]
