need a little favour from you guys. Somebody from UK emailed me and told me that my blog was down, and apparently, the domain had expired and all it was showing were some Adsense ads.
There is still a lot of manual work to do. Just tried it today. You still need to select the category you want to list and also, manage each directory requirement i.e reciprocal requirements. Not all sites listed are free listing.
Have you tried or checked out addurl.nu? 900+ directories listed, and a submission service also available.
