Can i make it work 2 content modules at the same time but with diferent names? One in location "user 1" and other on "user2" for example? Is there any conflict?

It depends on which module, some modules come with an option to set an ID so that you can have more than instance of the same module on the same page, it depends on the function of the module.

Which module do you want to use and have you not tried it?

I was trying to use "mod_k2_content". I already put to work the two modules. I wasn´t setting them right.

It works fine now.

Thanks Simon
