Insane price for something that is only extension! It works alright but it's not worth to buy! Problems with installation, quite hard to make it work etc... Crazy! It's even more expensive than Jomsocial itself!
(Price for one domain name for Parainvite + Parainvite Pro = $144 !!!)
Owner's replySome people has the idea that just because ParaInvite integrates with JomSocial (or CB), it is considered a sub-component and should be cheaper than JomSocial itself. That is a very warped way of thinking, and cannot be further from the truth.
Imagine another viral marketing solution that functions exactly like ParaInvite, minus the JomSocial integration. It will be a lot less useful, and much more easier to develop.
