For anybody who uses osTicket you may have noticed that it is no longer being developed and it has been two years since the latest update. I want to switch to a open source ticket software which is supported and updated.
Any tips on what to use?
I have obviously googled and found some great looking solutions but I would be interested in getting opinions from people who actually use alternatives.
You should consider OTRS - it is open source, and actively developed. It has a strong company backing it, a vast number of bigger and smaller companies using it, and it has a strong community with active mailing lists and forums.
