Please use the following signs while posting a question or response. These signs would be highlighted at the left hand side of every question and will let people know whether someone requires an answer to the question or has an idea etc. This will make our interaction quick and easy and increase our productivity.
1) Add a question mark while posting a question. This will allow other people to know that the question needs to be answered.
2) Add a "bulb sign" when you have an idea to solve the problem but are not sure whether it would help or how to proceed with the idea.
3) Add a tick sign when you answer a question so that people will know that the question has been answered and can refer to it for studies.
4) Add a note or blank page sign for any miscellaneous comments, suggestions, comments etc.

It would also be great if you could add you current preparation status or GMAT scores in your signature so that we could help you with a better understanding of the specific areas you need help in.
