Just a note to make readers of this board aware of a two part article, in Canals and Rivers Magazine, written by someone who decided to go down the shared ownership path, did their (impressive) homework, and then bought a share.
The second (more detailed) episode appears in the current magazine (June 2007). If you want to read the first episode, I guess you could get hold of the May 2007 issue from the publishers A E Morgan (try kriss@aemorgan.co.uk). Or if that doesn't work, we have a copy and a photocopier (!)........ and an e-mail address (above).
