Hi RonH, I might have an other alternative for you.
There is a website,
http://www.instapaper.com/ , where you can "save" a page so you can read it later on.
You can download it in many format, including epub. Also, you can RSS feed it into calibre in "news", so it automatically sync next time you plug your kobo.
I can give you a step by step if you want, but it is fairly simple.
But here a rough step by step :
1) Create an account on
http://www.instapaper.com/
2) Bookmark the READ later icon on the website.
3) Go in calibre and in RSS feed, find instapaper, then add your account name + password(by default instapaper doesn't need a password.)
3) Find a webpage you want to read on your kobo and click the bookmark READ LATER.
4) Go in calibre, update RSS feed
5) Then your instapaper feed should be in news
6) Plug your kobo
7) Read
It is a rough guide, as i am not on my main computer where i have my kobo + calibre, but i am pretty sure it was something like it. But if you would like a more precise guide, just let me know.
** But this way doesn't fix the size, so if you can't read on the default size, you will have to run it through "the kidintheblock."
