About trial versions, a strange idea has just occurred me: has anyone out there thought of offering a trial in two separate periods? For example: 15 trial days = 1 day now + 14 days starting whenever you want it to. This is to solve the problem that when I stumble upon a service that has a trial period, I have a strong urge to see what it's like, but am afraid that I will forget about the service for n-1 days, when I will get an email telling me that the trial has ended and I haven't gotten around to explore it fully. Say, for example, I want to try out a project management suite. If I have a split trial period, I can explore the features and overall feel of the product for myself on a day and then prepare my workmates to use it in a test project, and only start the second part of the period when we are ready. Has anyone thought deeper about the advantages and disadvantages of this?
