Congratulations to both of them. I too believe these 2 cases are genuine.
The only thing that irritates me is, why the hell won't they post more details? Just saying "My petition was approved today" is meaningless without any details (at least the FP date). Sometimes typos occur. If RD/ND is also provided, we can at least check if he/she did their FP on 01/28/03 or 01/28/02 (I hope not).
