I am getting problems when a user tries to send text to another user. The information does not seem to get there. It is either in how the client reads from the server or in how the server handles and sends the information so I will include both parts:
Server

for ( int i=0; i <= fdlarge; i++ )
		{
			if ( FD_ISSET(i, &tmp) )
			{
				if (i == top)
				{
                    	// Handle new connections
                    	int size = sizeof(client);
                    	if ((newfd = accept(top, (struct sockaddr *)&client, &size)) == -1) 
						cout << "Error in Accept";
                    	else 
					{
						con[count++] = i;
                     	     FD_SET(newfd, &master); // Add to set
                     	     if (newfd > fdlarge)
                     	         fdlarge = newfd;
					     recv( newfd, name, 30, 0);
					     announ = newuser( i, name, &client );
					     tserv.announce(announ, con, count); 
						   
					     // Show Status
                    	     cout << "selectserver: new connection from " << inet_ntoa(client.sin_addr) << endl;
					}
                   	}
				else
				{
					if ( (bytes = recv( i, buf, sizeof(buf), 0)) < 0 )
					{
						cout << i << " disconnected";
						closesocket(i);
						FD_CLR(i, &master);
						return 1;
					}
					else
					{
						user = getuser( tserv.getIp( i, &client ) );
						for ( int j=0; j <= fdlarge; j++ )
						{
							if ( j != top )
							{
								user = strcat( user, ": " );
								user = strcat( user, buf );
								send( j, user, strlen(user), 0 );
							}
						}
					}
				}
			}

Client

		if (FD_ISSET(top, &readfds))
		{		
			if (recv(top, rec, sizeof(buf), 0) <= 0)
			{
				cout << "Server disconnected." << endl;
				return 0;
			}
			else
			{
				rec[strlen(rec) + 1] = '\0';
				cout << rec << endl;
			}
		}

Which else are you talking about? And why does using the recv there go against the idea of select? That recv is there because the client is sending his screen name over to store on the server.
