function get_archives($type='', $limit='', $format='html', $before = "", $after = "", $show_post_count = false)
type = one of 'monthly', 'daily', 'weekly', or 'postbypost', empty = use option configured type
limit = limit number of entries/months/weeks/etc. returned
format = one of 'link', 'option', 'html' or empty
link will output link rel="archives" entries
option will output option value= entries for use in a form
html will output list item links
empty will use the before and after params
before is for text/html to be output before the link
after is for text/html to be output after the link (and also after the link but before the closing list item tag in html mode)
show_post_count = whether to show a count of posts for that month (only works in monthly mode)
Hope this helps,
Mike
