Might does function as a past-tense form of may sometimes, especially in reported speech:
"I may go there tomorrow".
Paul said he might go there the following day.
Some speakers use may for permission; most use can:
May/can I use your computer, please?
For some speakers, but only for some, might suggests a lesser possibility than might - We may/might come over tomorrow.For others, however, there is no difference between the two forms. There are some speakers who never use may at all.
If you have specific questions, we'll do our best to answer them.
