You are looking for a redirection from the home page to the next. If you create your text only page as the index/home/default, whichever you call it and enter this line in the 'head' section:
<meta HTTP-EQUIV="Refresh" CONTENT="5; URL=click here . yourwebsite . co. uk / nextpagename.htm">
then it should redirect after 5 seconds. Take the double spaces out in the above URL, they are only in to stop a non-existent link appearing in the thread. Remember you will have to rename your current index page to something else, maybe "main" or something like that.
Hope this helps, although I am sure Taran will have a better way...!
