I think it's great that singingscrapper wants to share her template and look forward to seeing it "out there" for more people to use, but I think there's a bit of a problem.
After quite a bit of searching/clicking/scratching-my-head I've managed to find where the templates are held.
You can find them by going to the Scribus page on SourceForge.net, then clicking on "Files", then "extras", then "templates". Is it just me or is that a little difficult to find? It's probably basic stuff for developers but for the average user I doubt many would get there and would just give up. (How a normal user would upload anything there I haven't a clue.)
There is a wiki page that says to put templates on the "Sample Docs and Templates" page but that doesn't seem to exist. Also, personally, I'd say that if someone is looking for templates I don't think they'd look in the success stories section, they'd most probably search for "templates" then find nothing that stood out and then stop looking.
Would it be possible for someone to create a much more visible area/page, possibly on the wiki, where people can find and upload templates more easily? This "Templates" page could also give some instructions on how to properly use the installed templates too (some don't have any instructions). In my opinion this would help the community to grow by both making Scribus more "accessible" to new users and allowing people to get more involved by submitting their own stuff.
That's just my suggestion though. Maybe someone else has a better idea. I hope so.
