I was wondering if I could get some insight here. I have been ordained since 2007 and not many people know about my "revenednship" I am proud of it, but don't find it necessary to introduce myself as reverend or sign everything reverend.
Should I flaunt it or remain humble about it?

My original ordination was in 2004 to date I think there are less that 50 close acquaintances that have heard the rumour and less that know it to be true. This said, there are others that know but I felt it relative unimportant to tell everyone.

Some ministries require more publicity than others. Whether or not you need tell everyone depends on what your ministry is. A few times I have been places that telling every one was useful but sometimes it is useful to quietly watch and offer help just as a friend. Deciding when and where to use the title is sometimes difficult but I generally just goe by first names with people until a point when the title is absolutely required.

But this is just me; others have other opinions.
