Is this possible for multiple CB fields? For example, I want a group for males who live in Greece (cb_nationaliy = Greece AND cb_sex = Male)...doable?

No, it is single field condition only. Next release will have substitution based conditions where you could then do as you're wanting. As you'd compare 2 values whether substitutions, or static values, etc..

1. Kill me, but I can not find where I can customize this automatic grouping. How to do it?

Install the auto integration then navigate to the auto icon from GJs backend.

2. If this function is available, then it is adjusted only on the field "Country"?

No, the documentation is just showing an example. You can condition based off any field you want. Next release to be even more powerful.

The fact that I have all the users of only one country. I would like to automatically add them into groups according to different criteria. First of all, I'm interested in grouping on the field "City" or "Location".

That's doable, but you can currently only condition off of 1 field. However, you can have as many "Autos" as you want.

- CB GroupJive 2.3 RC

You need to upgrade. 2.3 stable is released.

Woohoo - This is when I will take the plunge in paying for the membership. This is exactly what I'm looking for. I'll be waiting for wonderful release of 2.4. With the next release, how difficult will it be to add/change these particular parameters? Thank you muchos.

It has a full backend GUI; so basically it's a couple clicks and you've auto group join, group create, or category create.. whatever you like.. you can have an unlimited amount of autos as well so possibilities are up to you. Simplicity is certainly there as setup is jQuery guided walking you through each parameter 1 by 1 and hiding irrelevant parameters based off selection.
