Ok cool - I could not see any structure to help Og handle manual  
schema changes.  As long as I can

I noticed this.  I'll have to take your word for it for now, sounds  
like black magic to me :)

Can I be any help with this?  I won't start working on any web apps  
until I have the tools to work BDD, so I'm happy to help get RSpec

I was hoping this might be the case, but without actually trying  
anything I had no idea.

Thanks - I think one of the best thing about programming in Ruby is  
the helpfulness of other developers.

When you say JQuery, do you mean <http://www.jquery.com/>?  If so, it  
looks pretty cool.  I watched some of the examples here: <http:// 
docs.jquery.com/Tutorials:Live_Examples_of_jQuery>.  Can you sum up  
in a few words how JQuery replaces RJS?  It looks all client-side to  
me.  Is it possible to use JQuery when the exact data and effects are  
determined by the database?

Whatever, it looks like I will have to learn JavaScript.  Don't  
supppose you can recommend a good book?

I don't speak any greek - could you explain what's going on in this

Yes it does - I'm sold :)  I have a few other things to get out of  
the way but hopefully I will be able to make a test Nitro app this  
week.  It sounds like the leap from Rails will not be that big, and  
it looks like I won't lose anything important (apart from testing for  
the time being).
