What Can Change On A Listed Free Site?

[horney]

Being a noob, I haven't done many sites yet. But it is true to say I can see a lot I could improve in the first half a dozen or so, even though they were listed with some of the bigger lists. Then there are the errors which don't become visible until later, even with an otherwise pleasing site.

Is it OK to change a site title? Or is that absolutely taboo?

Descriptions and other wording on the site?

Replace banner links with text links or vice-versa? (linked to the same place, of course)

Swap sponsor banners for more suitable ones? (ditto)

There is one free site which is already listed with every list which has checked it so far. I asked another list owner to look at some of my sites, including that one, to see if he'd let me submit to his and he pointed out a couple of self-made banners which could be mistaken for thumbs acting as links to the galleries. Hey, I only clicked on one instead of the gallery link myself today! Am I right in thinking it's OK to just go and put something like that right without telling anybody?

List owners, what have you seen done which is absolutely a no-no?
