Community Creator

Hi,
I've been using the community creator on here and can't work out how to delete fish or start afresh with a new tank. I have a long list of fish mostly reduced to zero in numbers as they aren't suitable, and it's confusing, especially as it tells me all the reasons why I shouldn't be keeping fish I don't want anyway!
Do I have to register? I don't want to register for yet another site, I'll just forget all the info. But I will if that's the only way.
Thanks.

And if you register and log in you can save several tanks. That way you get to play with different stocking without having to delete all the other options first.

I just use the same password for the CC and forum, the main difference is you log into the forum with your user name but you have to use your email address for the CC.
