yes, do a general page, and modify the 1und1 one accordingly, i.e. remove the stuff in there, and just point to your new page.
Makes a lot of sense to me.
Agreed. I'd be happy to test it out and work through any issues I find. I probably will not have time to get to it for a month or two but I will get to it and report back (or update the wiki) for corrections/additions.
It would also be convenient to include the list of pre-configured providers in the wiki, although it's possible to get that list by pretending to install and noting the providers listed.
