Hi George,<br /><br />Many thanks for your editing. I might have questions after I organize the paper but I will let you know if I do.&nbsp;<br /><br />I am having an in-class exam tomorrow and after. But on Friday and Saturday, I will need your service and I hope I can get the 2-4 hours one.&nbsp;<br /><br /><br />Wishing you a good night.<br /><br />Maya<br /><br />
