Hell All, I have asked this question before but things have changed a bit since then. Here is a link to my previous question. Salary Revision

So now I am more than 14 months into my job but still at the same pay level. I have had a couple of discussions with my managers and all seem to be very happy with the job I have been doing and are giving me more critical tasks to handle. There have been instances when they have wanted me to handle particular tasks in projects as a lead. As of now there have been no talks about a change in my salary but I feel I deserve one at this stage. I think maybe I should have brought this up in one of the meeting with my managers but I missed my chance then . This being my first job, I am really not sure how to start this topic and I am worried about how my managers would take it. I do not want to come across in a wrong sense. Any inputs on how to start this or what to talk would really help me. Thanks (.Net Developer - USA)
