I've been developing in PHP & MySQL on and off for about a decade now and I would say I'm an advanced novice at best. I've become very comfortable with CodeIgniter as of late, so it got me wondering: how much time would I be looking at if I rewrote osTicket based on the CodeIgniter framework? My main purpose would be to make osTicket easier for me to mod and extend (specifically I want to add the ability to have multiple clients/customers).
Any one have any idea what kind of time I'm looking at?
