Very good work JJ. Please allow me to act as a pedant. I don't claim to be an authority on the topic of grammar so feel free to ignore any or all of my suggestions as you see fit.
Page 2:
Move the ellipsis from the start of "just like you." to the end of para three. An ellipsis should be just three dots.
This is personal preference but I would reword the final para to
The advice within this document will be constantly updated. If you want an updated version it can be downloaded from [...].
Page 3:
Change "Well simply put;" to "Well, simply put:" or even "Simply put:"
The "i" of "central traffic island" should not be capitalised.
Change "(to avoid the door zone and to ensure cars only pass you when it is safe, without putting you in the door zone)" to "(to ensure cars only pass you when it is safe, and to avoid entering the "door zone")"
Change "This states that you must stop at red lights, if you ignore this rule, do so at your own peril, can expect to antagonise other road users and attract the attention of the authorities (who are increasing their prosecution of cyclist who jump red lights)." to ", which states that you must stop at red lights. If you ignore this rule you do so at your own peril and can expect to antagonise other road users. You may also attract the attention of the authorities (who are increasing their prosecution of cyclist who jump red lights)."
Move "and is in advance [...] " above the images, or the rest of the para below them.
Page 4:
Change "You will put yourself at risk for no reason, it takes so long [...]" to "You will put yourself at risk for no reason. It takes so long [...]"
Change "as you are bound to meet" to "as you might meet"
Move section three slightly higher to allow for spacing above the para beginning "As a golden rule [...]"
Personal preference, but perhaps change "If it moves away and cuts the corner, you will be in huge danger ..." to "If it moves away and cuts the corner you will be in huge danger of death."
Page 5:
Move "(if you choose to)" to after "left hand side"
OK, I've run out of time now. I'll come back to the rest of the document later. Or, if I've got the above horribly wrong and someone point it out publicly I'll hide and sulk for a bit and return to the fora in a few weeks under an assumed identity.
One last thing. I'd be tempted to put the Cycle Chat URL on the front page, along with a download URL for the doc itself (perhaps Shaun can provide a simple address for it, such as
http://www.cyclechat.net/beginners). With my configuration librarian hat on, it might also be nice to have historical versions of the document available as well, with a log of changes (not necessarily for the public, but for theoretical future editors).
