Just tried to log into my DB account and the site has changed since I last went. Is it still possible to play with fun money as I couldn't find this option?

Can some one please explain to me how to work out your edge? (I am NOT saying I have one)

I guess there must be some kind of formula based on units won in x amount of bets divided by amount of numbers covered ( I am probably miles out here lol)  ..... or something like that.
Would really appreciate some help with this.

If my terminology is a bit off please forgive me.
Is it possible to get a programme (Clicker ??..Bot ??) that would "sit" at an online roulette table and collect numbers and then "call" me (Alarm or some such) when an event had happened for me to start betting.
I know a bot will bet for me also but I would kind of like to do that bit myself.
Would it also be possible to arrange the numbers collected in a certain way?
What happens with these things when the casino "boots" you for not laying any bets during the collecting stage?
Just an enquiry at this stage ....
Thank you
Blood.
