How effictive is using free directories for seo? Are they a relevant link since they are listed (supposed to be) among similar categorized websites? It seems like a lot of work to submit to these directories because 3/4 of the time the submission is unseccessful, or the anti-spamware text test doesn't work properly. That's another question I have: On some sites I can retry and retry to enter the text on those boxes, and it says I've entered the wrong text (when I haven't). Could that be related to some kind of security software on my computer or something? Thanks!
