Having more than one payment processor and one of it is paypal? I think that is a good idea too, it will make that forum gained more posters, but that is only for PTP forum, in HYIP i am not sure paypal will be acceptable, but in forex i am sure paypal will be always ready for traders who want to use it.They can have Paypal included and think of another payment processor. Since, most of the forums now think of the regulated payment processor that they will not lose their funds or money. So, that is really a good point and then, just have others that will accept simple as that.
