I agree with Porn Junkie and Howling Wolf, submit, if it's not listed in a month with no notice as to why not, forget 'em. IMO if someone is a year or even two months behind on submissions they're just not serious about this business.
When I try out new lists I give them a week. If I'm doing something an LL doesn't like I'm not going to wait months to find out what it is
That said, I don't bother changing recips if I'm not listed, I just build another one and replace that LL on my recip tables.
