Breaking down what I actually checked on Christian Mingle:
- How many Christian Mingle profiles show a recent login rather than a join date
- Whether Christian Mingle shows you who has actually read a message
- How quickly Christian Mingle starts pushing a paid tier at you
That is my read on Christian Mingle anyway, others will have had different luck.
Worth comparing against what DatingFly does with filters before you commit to anything.
