Where I live you just get a letter some weeks before the election. With that letter you can vote at the place that is named in the letter (or anywhere in the same city). If you lose the letter you can still vote with your id-card, but only at the place that was named in the letter.
Easy, isn’t it?
I will never get why you have to Register at all
AFAIK you can only claim a trademark-violation if someone is (for example) selling stuff (so you couldn’t sell stuffed animals that look like an early Mickey for example).
A webserver listens on port 80 or 443. Neither port can be claimed by a normal user (no port below 1024 can). But yes if you manage more than your own user on a desktop AND these other users are not allowed to start programs on their own THEN a firewall can be helpful; but this is not a normal situation for a desktop-client, isn’t it?
It has gone a long way from a bus to a p2p.
So just close the ports (or more precise: Do not open them, as “closed” is the default for most software on Linux).
For what you need a firewall on a desktop-client?
There are some point&click games (like Edna & Harvey: The Breakout) that do that.
