Ok here we go.
1. Well LL's like it when they get a bit of return traffic from freesites. If you put up more recips on your warning page you get more traffic to that page which means there's a higher chance that the linklists get traffic back from your FS. We all need traffic you know
2. Some places have this rule, but lmost of them haven't. If they do have it I assume spunk on the lips is not allowed. Everything from penetration, to cunnulingus, to whatever sexual act won't be allowed. Only naked chicks that do nothing
3. 98% of the time you'll get your recip before you submit the site. Adulteverything is an exception I guess. And with no changes to the site most of us mean that you shouldn't put up different content, adding 5 more sponsorlinks, etc. Changing a recip from a site that has declined you or something like that won't do you much harm.
In the linkback field you put the URL where you've put the recip. This is so the script can check if you put the recip up or not. Usually this is the same URL as your index page.
4. Always use the same email address. It doesn't matter if it matches the site's URL or not.
There ya go
