I cannot rez an object because my "parcel is too full." What can I do?

[ShariAllyn]

I am trying to rez an object but keep getting an error message saying my parcel is too full. What do I need to do to fix this?

Hi there,

each parcel has an allocated prim count, you have used up all your allowed prims, so in order to rez something else, you first need to pick something up.

World > About Land > Objects will tell you what your parcel's capacity is.
World > About Land > Objects > Owned by Others will show you if someone else has rezzed something on your land, you can also return their objects from that screen.

If you need more prims, you will need to buy/rent a larger plot of land, or buy/rent another parcel on the same sim to combine the prim allowance of both.
