I'm sorry to say this bone, but you got ripped off. Most search engines go out of their way to block such automated scripts from
submitting. ie:
http://addurl.altavista.com/sites/addurl/newurl
The only way to submit succesfully is by hand.
btw i get
http://searchservices.lycos.com/sear...t_overview.asp
when i submit to lycos. I dunno where you got that isubmit.com thing.
If you wanna pay for inclusion, do it with the SEs themselves. Yahoo is $600 for adult sites and they are VERY hard to convince so only do it if you think your site is cross-browser compatible and has relevant content.
Inktomi used to be worth it but since aol replaced it with google, it's not what it once was. Try DMOZ.com if you're not already in there it might help.
