:Dear RifThanks for the comments; I had already anticipated the need for pre-Nineteenth century gunboats (and, as you say, gunbrigs), and I know how I'll get them in there very easily.  Can you send me the details in the same way?  I'll take a couple of weeks at least to run through the current gunboats/gunvessels page, ensuring that the details are error-free (which I doubt, given my errors of transcription that I've already uncovered).  It also occurs to me that torpedo-boats are not listed anywhere - I imagine another (but much shorter list) is called for.  As for the format, it has the very strong advantage of making the class pages simple to write - as I'm doing with Mariner class gunvessels.  What I could do is simply delete the lists as the class pages get filled in.   One question I do have for you is: have I missed any entire classes out, and do all the vessel listed count as Royal Navy vessels?  I'm thinking particularly of Magnet, Canada and the like.  I've left out all the colonial service vessels (but not HMS Diana (1823)) for that very reason.Thanks for all your help - without it, I wouldn't so much have started.Yours,
