Donating $$ visibly in the box by CHECK seems to help since a couple of brothers will see them and possibly discuss them.
That is the key to being accepted. As one guy (now an elder) told me years ago when I temporarily thought I would like to be married, "Don't get married. Just hire a couple hookers when you are in Las Vegas, come back and say you had a moment of weakness and you are sorry. Then make a BIG contribution to the congregation, maybe even slip a few Benjamins to the elders, and all will be okay."
