To remove the rank restriction extract the addon and remove the "and tal:IsAdmin()" from line 7 of lua>autorun>server>voice_amp_server_init.lua

The whole of this line is "if tal:GetPos():DistToSqr(lis:GetPos()) < wep:GetDistance() or (wep:GetAllTalk() and tal:IsAdmin()) then return true,false end"

It should look like "if tal:GetPos():DistToSqr(lis:GetPos()) < wep:GetDistance() or (wep:GetAllTalk()) then return true,false end"



Once you have edited this line create a folder containing all the contents of the addon including the lua file you have just edited. Upload this to your "addons" folder on the server or in your client for single player.

You will have to unsubscribe from the addon for this.
