Open Source

Term coined in March 1998 following the Mozilla release to describe software distributed in source under licenses guaranteeing anybody rights to freely use, modify, and redistribute, the code. The intent was to be able to sell the hackers' ways of doing software to industry and the mainstream by avoid the negative connotations (to suits) of the term "free software". For discussion of the followon tactics and their consequences, see the Open Source Initiative (http://www.opensource.org) site.

Opt-in

To purposefully accept some situation or condition ahead of time. For example, to opt-in to an e-mail campaign means that you want to receive periodic newsletters or information, which may include advertising from the publisher or third parties. An opt-in program implies that you can cancel the service, or "opt-out." A lot of spam is sent out under the guise that, at one point, you did opt-in for the program, which may or may not be true.
