+TOR SHELL\n\
+=========\n\
+Until I finish testing and add the code to customize its parameters in the gui, these are the defaults:\n\n\
+Hostname: $tortle_hostname\n\
+TOR Port: $tortle_tport (Redirects to local port $tortle_lport)\n\n\
+
+TOR GATEWAY\n\
+===========\n\
+At this time, it is just a regular TOR Proxy but my plan is to evolve it into a much more convenient and secure fully isolating Gateway.\n\n
+The LAN Turtle (with its two ethernet interfaces) is clearly perfect for that purpose, although I have to figure the best way to do it without 
+affecting the operation of other modules/functions that may be running at the same time (some iptables playing needed).\n\n\
+In the meantime, please notice DNS or other well known leaks are NOT being actively prevented. Use it accordingly.\n\n\
+TOR Proxy is in $tortle_socksip:$tortle_socksport\n \n" 33 72
