but dunno where to put it in source

In your sources....

Btw, did you open the server during making a compile or taking a ready pack from here or somewhere?

but dunno where to put it in source

Index: head-src/com/l2jfrozen/gameserver/handler/voicedcommandhandlers/ChangePassword.java

Index: head-src/com/l2jfrozen/gameserver/thread/LoginServerThread.java

and so on

Btw, did you open the server during making a compile or taking a ready pack from here or somewhere?

I think it's obvious he's using precompiled, since he don't know what's the sources.

compiled by a friend ...

So, you're not able to add this code. Read any tutorial, check frozen's forum, surely there is one. Download sources and add it.
