Making suggestions, expressing certainty and expressing doubt

Marc: We could consider hosting a community blog a good idea because we could update everything we do when we meet. We could show them how our community works and how we organize.

I'd be great if we could create an information center for visitors to the area because they could know a little bit more about it.

What about setting up a community library? It would be a great idea because reading is very good for learning.

There's no doubt we're going to set up a community library because we all think its better than reading in a computer. It is also a good way to communicate with other people and discuss about books and magazines and you can discover new writers too.

I'm not really sure that host a community blog is a good idea because we need a lot of time to organize and share thinks on it and we don't have it.
