looking for good free or open-source Help Desk software.
And by Help Desk Software I don't mean development issue tracking (which is slightly different), I mean software that is optimised towards tracking support requests from the user base of a small-medium business. So something like ZenDesk, rather than something like JIRA.
Particularly interested in solutions that also integrate asset tracking.
I'm aware that there's a big list at http://www.opensourcehelpdesklist.com, but I'm hoping to hear from people who actually have evaluated some of these solutions.
(While I did find a few similar questions on StackOverflow, the answers tended towards issue tracking systems rather than helpdesk systems, which is why I'm asking this question again)
