Hi Alec
Look at any book review and you'll get the format.
Basically you need an Introduction, Content and Conclusion to the article. Take about 12 decent pictuers or more to give people a feel of the content and then you click on to the review button, you'll see a Submit you're own Review link.
Copy and paste the text in, fill in the boxes that have drop down menus, Manufacturer, period etc and when you're ready press submit. The pics I assume you could email to Gunny.
The review is your personal opinion of the quality, value, content etc.
PM Gunny and he could advise on who deals with what on Shipwrights.
Look forward to it.
Al
