Module development and code questions

I've installed the current version of ecommerce on 4.7.2.

1) I don't see anywhere to create a store. I can only create products. If I go to goodstorm.com/store, I see their store. On my site it's at /product.

Is this the way it's supposed to work?

2) Can I allow ten users to each make a store, so that there are 10 stores?

Just installed Chatbox in Drupal 4.7. Works fine, but there don't seem to be any options within chat, such as /help or /?. There is only a reference to IRC style chat, even with the /me command. I'm not familiar with IRC, and the /me command doesn't seem to do anything.

So are there any in-chat options in Chatbox?

I tried to convert the Recipes module:

http://drupal.org/project/recipe

to 4.7, but it's not yet working. Could anyone assist with me this? What I have done is available here:

This is my edited version of recipe.module.

Thank you,

Is there a way for me to augment the access denied page with a custom message when I deny access? e.g.

"
Access Denied

Why? Well, you've already uploaded 20mb of content, and if you want to upload more you must purchase a premium account.

Thanks in advance for any ideas...
