Return to Question

I have a vector layer with polygons A, and the second with polygons B. Polygons A includes/are intersected by several polygons B.

I want to join the data (just names of polygons) from polygons B to polygons A (in result polygon A get a field with all names of polygons B witch are intersected by them).

Polygons B are not a 100%-correct. Actually borders of B should be drawn in the same line of A border, but they are not in many of cases. So is there any way to tell qgis to join all of intersected B to one A but only if specified minimum %area of B is in A.

The last (I hope) question - output data A includes repeated data (ex. screen). How could I get rid of duplicates?
