Meant to post about this a while ago. I’ve set up the DoFollow plugin, which disables the automatic rel=”nofollow” that WP adds to links to combat comment spamming. Akismet is doing a pretty fine job at catching spam, and I mostly moderate comments anyway, so I’m happy to provide Google Juice to people whose links end up on here 
You can set DoFollow up to remove the rel=”nofollow” restriction only for comments older than a few days old, so even if spam does get on here, it’d have to stay for a few days before it’d have any effect - it would have been deleted within that time.
Congratulations on dofollow
join the bumpzee.com group as soon as you can 
Jump aboard! The bumpzee community (not just the Dofollow mob) is a nice little community right enough.
