I had been using Mezzmo for a while before finally shelling out and purchasing a licence. I'm glad I did, it's a fantastic product and the price is great. However, and I looked thoroughly, I couldn't find any mention of the licence needing to be renewed in the future. I know some software requires the purchase of new licenses when they upgrade a major version number. Is my Mezzmo licence lifetime, or if not, at which point will I need to update/renew my licence to keep using all future versions of this great product?
