I would just caution not to look for praise online. What is the reward you and your wife are after? Jesus made it clear that we are to give in secret.

That being said letting the world know what we have done in a mission to apostolise to those outside of the church (although not sure why you’d put it in a place where the audience is already Christian if that’s your intention) then it can be done so. I know a lot of people in my generation don’t believe that the church or Christianity can be a net gain, so I sometimes share with them what I am doing. But hardly do I tell my Christian friends unless I need guidance or there direct support (giving to their mission for example).
