When playing online, I don’t see any servers.

Thanks for the advice about pLan – I’ll try it when I get the chance. By the way, can you have both Hamachi and pLan on one computer? And can you run them simultaneously?

Of course, you can. Unless you have a dial-up connection – I think one program will significantly interfere with the other in terms of resource consumption and internet speed. P.S. When we played through pLan, I saw “Sila” and many others from Battle.net online, so there’s already a workaround for Battle.net.
