Well, what are those specs? If you want to send them by e-mail/pm - OK.
Thanks in advance.

Hmm, I'm not willing to host it myself really, my internet is not very fast and so is my PC. I also don't have a second PC.
So I'm really looking for some free host.

Hello,
I want a small demo host.
Now does someone know a good free demo host?
I want it to be up 24/7, but if not possible, please inform me of other possibilities.

For the router thing, try connecting to your router, then somewhere you can say 'port forwarding' and put the mentioned port to your server. Hope this helps
