What's your budget ?
railsplayground.com is pretty cool.
Yeah. Level 2 Developer plan looks like a good start.
Try #rubyonrails irc channel at irc.freenode.net
And nop, I run my own server. But I've had good experience with railsplayground in the past.
Ok, thank you for answers, i don't know how to use IRC
My rates are 20$/query 
I think hostingrails is better than site5/dreamhost.
Hi There,
I have been checking out hosters myself and am looking at OCS Solutions.
I have heard good things and they have just updated their web site, with a good range of flexible plans.
