Hi europeanmike!
Great to heard you like OSClass and you're working on the german translation! Thanks!
Which plugin are you trying to use? (houses, cars, jobs,...) We faced the same problem some time ago, we're few people developing it, we know we could improve the plugins. We have that on our lists, but tell us, do you have any specific idea you wish to see done?
You're correct about "pages", you could make a new one and link it wherever you want. If I remember well, you could find and example on "default" theme, at the footer, they should appear. Pre-defined pages are emails/notifications/alerts we send on specific events such as a new registration, you're able to modify them, but not to delete them. User-made pages, were intended to serve as "Terms of Service", "FAQ", "About us",... or anything you want. We also have in made to make them non-static (that you could include some dinamic elements).
Which extra-fields do you need? If we find them interesting we will include them. If not... don't worry! We also planned a custom-field add-on (but you probably will not see that in a near future).
Thanks a lot, we really appreciate your feedback and opinions!.
