Re 1 Yes that s fine although I ll hold off until there is more discussion on 2 Re 2 It s just personal opinion but the redundancy in a category like Pages with X is distasteful to me A category is a list of pages so it s pointless putting Pages with in the name For articles we say Category Living people or Category 1961 births It s not Category Articles about living people or Category Articles about people born in 1961 However I m pretty flexible and am happy with the outcome of a discussion although I hope we could attract a few opinions The good news is it would be very easy to change the category names see all categories in Module Convert text Re 3 Yes only one message is displayed no matter how many errors are in a convert but each message has it own category so there is no realistic way of putting Convert error last see all messages in Module Convert text for the full story Looking at the wikitext shows the category for each message Some expected errors have a dedicated category with a fairly obvious meaning Convert dimension mismatch Convert invalid option Convert unknown unit Other miscellaneous messages are in the generic Convert error category
