Same guy going by two different names. If you have recently received PMs from
paulmighty or
Jackmx you have been the target of the typical scam involving Want-to-Buy ads. Just delete those PMs and if you have already started emailing correspondence based on them.... stop!
Scammer cruises the WTB adverts in the TP and sends a PM to the poster claiming that he knows somebody who just happens to have what you need. It's never he himself but always his buddy. This time his buddy is supposedly in Texas, just like he was a couple of weeks ago. But... and it's a big but.... the guy sending you the PMs is sitting in Nigeria.
Don't fall for it! If you get PMs from a newish member that knows somebody who just happens to have whatever you posted a Want-to-Buy advert for exercise more than the usual due diligence. If in doubt do not hesitate to report the PM to the moderator team by forwarding a copy of the PM or by clicking on the icon that looks like this

-- it's up in the upper right corner of the PM.
