I too am cool with custom recips, colors, even custom text as long as it relates to the category you are submitting too. I think it looks a LOT cleaner when you build your sites that way. Plus you can put more recips in a table and have it look neat then you can when you use each of our recip tables.
This makes me think of G.A.S.S for tgp submits. I like that tool alot, but it is sooooo out of date, when I went to use it for some submits awhile ago, I ended up with viri in my computer checking out tgp's for rules in their data base that when I went and visited were gone and viri and dialer laden pages had been put up instead.
I can picture the data base for this... I started doing data bases in DBase II and Fox Pro, that dates me, lol. You would almost have to make this some kind of membership or fee based to make it worth your while to keep the recip tables up to date...we do like to change them for seo reasons.
But I for one, if it was reasonable cost, would use a service like that. I submit to small niches, and change up on niches from time to time, and it is always a pain in the butt to initially build all my tables....sometimes takes longer than building the first site in that category, lol.
