I decided to deactivate the "nofollow" with the Link Love plugin (found via Andy Bear list of dofollow). What does it mean for commentators? After a certain number of comments( less than the default 10), you will have a backlink. That's easy! I like that plugin because it give me some control over spam. I may change that number if I need to. I got the ideal from Kumiko. I prefer that method to the 2 other ones because it's the honest one. Btw, Kumiko has new domain and she's giving me a chance to make money online too with her new Cash Quest Competition!! If I win, I may make another contest(I like them) with that money but I will keep the rest for me. ;) Good luck and do comment! Edit 1: I had to remove it because it cause a problem with comments. I used another plugin Edit 2: I'm using this one: http://kimmo.suominen.com/sw/dofollow/. You can give a number of days before removing the nofollow. It may help with spam.
