# Foxhound :
JSRS is for Arma 2: Combined Operations and nope you can not change that.
If servers enabled the signature check it means they allow only specific addons. If they did not allow JSRS and you try to join that server you will be kicked.
Make sure you also installed the bisign files which come with the JSRS soundmod (should be in the same folder as all other pbo files).
To be able to play in MP while using the JSRS soundmod make sure to join servers which allow its usage or join servers which do not check signatures, but in that last case your game will probably be destroyed by little kids with to much time and lack of education.

Thanks Foxhound, I was not aware of that :)
I am kinda new to this whole modding thing. Is VopSound known to work with vanilla servers?
Thanks again :)
