"Nocturion" and "Seaport" are both sort of building games you can play free. I think flash style? I'm not really good at knowing these things (I think they're still around? I heard about them a year or so ago)
"Eyezmaze" has a bunch of them...
http://www.eyezmaze.com/ (It's mostly puzzle-style quick-easy games that you play once or twice but not ongoing games)
Then there's Legend of the Green Dragon, which is text-only RPG (well, maybe some of the servers use small icons). That one, lots of different servers around so you just have to choose, and there are usually variations between them, things like day length and which mods they have, etc. An older game.
Kingdom of Loathing is... well, rpg in style, but.. I don't know! Does it count as a point-and-click since you click things to make stuff happen?
Gothicats is another pet-collection site with a forum. It's mostly French but also has an English subforum and English-translation setting.
