Other link lists will no doubt have different rules/procedures, but if you get listed at Hadafew (you'll need to apply for a pass over at
http://www.hadafew.com/submityoursite.html) then your site will potentially be listed forever (forever in this instance is less a universal constant than a measure of eman's chances of long-term survival, which at present appear to be surprisingly good).
We're looking for people who build good quality sites, with no marked sponsor content, and a eye to the long term.
If you want to establish a lasting relationship and share quality traffic, we'll be pleased to welcome you aboard.
