// close topic

hi!
is there a way to close a topic, so nobody can write at it anymore, but the topic still exist?
for exampe somebody asked something, and it is answered.
now i wanna close it, because its answered.
but i dont wanna delet it because everybody could read it.

maybe instead of "answer" there is a button with "closed" or something like that.

u know what i mean? hope so.

help pls. thx

mike
