I've never tried taking out an in-game loan before utilizing the forums, but it was rather more awkward to find than I thought since its buried in the "Sirius News and Commerce" forum.
I propose adding a new subforum just for loans to attempt to streamline the process a little, using the search function it is a little difficult to see which 'loan service' is still active.
I would however just encourage you to scroll back through pages, Fletch Though if certain loan services are closed and inactive the owners should label them as such and perhaps we'd invis them.
The way I see it, loan services are not a big enough portion of that section to get their own subforum, and plus, that'd leave the main "Sirius News & Commerce" section with no more actual use than people posting a news article every once in a blue moon.
