I am guessing that whatever Ramster just said is absolutely correct!
What I just looked at your link, it was a gallery with broken images... so if that is what you are submitting to link lists... it wont get listed
If you have server problems at the moment... dont submit! Wait until its all good.
If you are trying to list a free site... then show us that! and you will receive a lot of good advice.
I wish you well with your sites and it seems like you have a good source of knowledge in Ramster... take that and use it... Most link lists will list most sites that are half trying... and you will recieve great traffic and the added bonus of some passed on PR to your site.
Good luck
