One other note, though - even when the site is running site design is not a factor in the decision of whether to list a site in the ODP or not.
The phrase "content is king" applies.
You can have the worst-designed site anyone has ever seen (as long as it is readable and links work) and it will get listed over a site full of well-designed garbage any day.
There are several webdesign forums that do offer the chance of a site review. They can critique your content, layout, colour scheme, graphics, coding, linking, or anything else you need help with. Solicit a LOT of opinions. Don't just go with the first replies.
I can assure you that we will look at every suggested site.
I only can not predict when this will be done.
