Thank you for that reply - I do hope that is the case. However, I've seen other wordpress members on this forum strongly demean the use of pages, saying that it was "like bringing a donkey to a horserace" in terms of SEO.
And there still is the user-friendly issue that I would like to be able to organize my content via tags and a nice table of contents, but it seems like I have to choose one or the other. Right now I like how the table of contents looks using "pages", but it looks like I'd lose that functionality if I went to "posts". However, I'd like readers looking at one page to be able to check out 3-4 similar pages via a "tags" function, but it seems like I can only do that with "posts", not "pages". I still don't think I've understood exactly why I have to chose one or the other.
Are the any ways out of this? The best I can imagine is just having to imbed a lot of direct links into my pages, which isn't really going to jive with the appearance I was looking for.
