Mighty developers be thanked, you can now marry and foster children in Glitch!
Click on a fellow glitch (of any gender) and choose "Propose".
If they accept, you're officially Glitch-married!
After some time together (3 weeks, I think), the new action "do it"
will be available. If they are in the mood, you will get a "baby egg" (yes!),
which will turn into a baby glitch as soon as a new player registers to the game.
You can imagine the rest...
