tend to agree with jh3. as an early user of trellian i can tell you that it tends to develop no real traffic for a site (but affiliate links with trellian tend to do well).
if you just want a small utility to add a page to the majors you can get that anywhere for free...I have one I will gladly give you if you like.
this is the software i use:
GRSeo's search engine optimizer
webposition
html validator
GR's keyword density analyzer
Some of these (webposition) have a bit of a learning curve but i still think there is value in taking the time.
but in the end, it's like html...i use dreamweaver but you just have to know how to write it by hand in gold old notepad.
was this rambling post any help? if you just want the submittal software let me know dirk and i'll post a linkf or you to download.
