Hi,
I did that and tried. But I'm sorry, I really don't get it. I am trying it here:
http://www.ilkegenrich.com/blog/web-design/
It's actually about being able to open the same text in Dutch and German on this page. Two read more tags would be best, but I think that's pushing it, since I seem to be able to only choose one "Read more" text. So I can create the link, but the arrow doesn't appear (only '&rarr'), and the lines I wrote following the read more tag don't show at all, just the link disappears.
Any idea? Or do you recommend looking for a hideshow plugin or something like that?
