On a site with open membership, DBR automatically results in the user becoming a site member and watcher of the site. Open sites are "sticky" and acquire all new registered users.

Again, I don't think this is a good idea. The default action should be that all new sites joined by a user are NOT watched. If they find themselves continuously clicking on 'watch site' then they can set it to automatically do so in their user settings.

If I came across a website and joined, then started being spammed with emails from edit changes, I'd do two things:

• Block the domain from sending me mails (send them straight to the spam folder and "report spam" in Gmail)
• Never visit the website again

This is exactly the same situation as Wikidot puts users into.

Auto-watching is useful for websites that I own, but except for me being a part of the community now, I wouldn't want to watch any other sites. I'd rather just visit them when I have time and read the news, blog, etc. for updates

Instead of The verification email has the title "Confirm your comment on websitename"

How about this: The verification email has the title "Confirm your comment on %%site_title%%"

;-)

I think there should be a way for private paid sites that membership to wikidot be transparent, i.e. not visible. Private members would know registering to the private website, not to wikidot.

It would be great if admins could send an automated message to new site members — os if, upon completing the sign-up process, the user were directed to a page containing such custom text. How about that?
