I've got today an idea:
You should publish the download links for NIS/NAV/360/...etc. (all (localized) versions too) to a read-only maintopic. And if a new update comes, you can simply add a new post to the topic with the new links helping the users to get it (after the managed LU session of course ;)).
I thought this because if I want the new setup files (don't want always use LU to get all updates, and install the new ones is faster too) it is HUNT for them... Don't know when it will be available for download, and with the localized versions there are always more "trouble".... Ie. I have noew the Add-On pack's updated (3.1.0.7) setup package, but the 16.1 NIS install file still not on the hungarian servers (and I get the update via LU about 2 weeks ago)....
I can imagin it so:
under NIS/NAV/360/Other topic comes this: Download Links
When click on it: it will load the topic list:
NIS2009 16.1 update
NAV2009 16.1 update
NIS2009 retail
NAV2009 retail
N360 2 2.5 update
N360 2 2.4 update
Ghost 14
NSW 12
...
And in them the links:
