Prayhard,
To activate your PM, you can go to edit profile on the top left hand corner of the page. Click it. Then they will prompt you to enter your password. Then under preference, you just un-tick the Do not send private message sentence. Then save. After that, we will be able to receive PM le.
For the OPK, I am waiting for you to PM me. Just click on my name and you can send le. But someone already send me a PM on the OPK. Dunno if she did buy it from my friend or not. Maybe you PM me le, then I reply u with my friend's email then you check with her directly. If not, I can also give you my current supplier's contact.
