those with smaller requirements or budget could rent pages from a main information provider rather than from the post office/british telecom. the main ip had to pay an additional £250 to obtain the privilege but could then rent out individual pages at a market rate. unlike the main ip, sub-ips had to pay a per-minute charge for editing online, 8p per minute at monday-friday 8 am-6 pm or 8p per 4-minute in all other times for sub-ips in 1983 (over 35p as at end 2014). sub-ips were restricted to pages under a 4 or more digit node within a main ip's area, and could only edit existing pages. sub-ip accounts were unable to create or delete pages or frames themselves.
