I am happy to show you a huge upgrade of "KC Groups Management" plugin. That will be a new Pro version. It have several improvements, which will do your life easier. Please look at plugin's page for more info.
Existing version will be there as "Basic", with half price. All existing clients can update to new version. Some of existing clients have it anyway. But there is no security problems, so maybe upgrade is not a good idea, as new version needs settings, which old one have not. Think again before upgrade.
Additionally, now I set "one site" and "developer" licenses, so you can have wide choose.
And last, but not least, you even can get commissions with my affiliate program. I do this with hope to help to bigger number of people.
Have a nice morning/day/evening! :-)
