Multiple domains: how to get key(s)

I have a Drupal website, reachable by about 7 different, unrelated domain names.
When I request a key, it only can be used by 1 domain. Drupal doesn't have an option to provide a multiple key case.

Can I Mollom instruct to "generate" the same key for all domains?

Several weeks ago I did send an email, but I am still waiting for a reply. I hope this forum will generate a quicker response.

I use Mollom in several sites and I didn't get any spam message up till now. I am eager to convert all my site to Mollom.

If all 7 domain names link to

If all 7 domain names link to the same content, then just choose one of the URLs as identifier for the key. If they are however 7 different sites using the same codebase, then you should create 7 different keys.

We must have missed the email sorry for that.
