Since you're a newbie, it would be best if you could send me the file by Email. I'll send you a pm with my address, upload it to tindeck, and then mail the URL and code for your reading bac.
Differently to podfic we all present the readings in our own journals. One of mine is here, as an example. You don't have to use your own journal, though, but can also use a community we created for just this purpose, rla_readings. You'll find some examples also there.
You can present your reading in any way you like, with or without the text, with images as some do; but what needs to be apart from the link to the audio file is the chapter title, and that this is part of the read_lotr_aloud project.
If you post this to your own journal it would be lovely if you also linked back to the community, and also give a link to the whole chapter once it's up, either in a separate post or as an edit to your reading, whatever you prefer.
When you "reading entry" is done, post the link to it here, please, where I will collect the links for the chapter entry which will look like this this.
If you have any questions, just ask! :o)
I can do this entry for you, too, if necessary.
