History
On June 16, 2001,
16-year-old Zef Hemel along with collaborators Jeff Lewis, Corey Chapman, T. Oswalds, and Matt Mecham released the first open source bulletin board written in

called YaBB 1.0 (Yet Another Bulletin Board).
YaBB 1.0 was the leading free forum software package at the time. It proved, however, to be inefficient and slow for active communities.
On November 12, 2001, shortly after the release of YaBB 1.0, a second program, YaBB SE 1, written by Jeff Lewis and Joseph Fung (from Lewis Media Inc.) with help from Zef Hemel and Christian Land (from the YaBB project) was released. Ultimately, users of this rough

port of YaBB also reported resource and security problems.
[
Lewis and Fung split off from the YaBB SE team to try a different approach for addressing the YaBB SE efficiency problems, security concerns, and to add new features. Lewis and Fung did a complete rewrite of the code][ and changed the brand name to ''Simple Machines Forum (SMF)''.][ On September 30, 2003, the first "YaBB SE/SMF" product, SMF 1.0 Beta 1a, was released.]
The development and support team for YaBB SE was shut down in March 2004 with hundreds of communities in operation, when the developers joined the SMF project. A converter was developed to convert YaBB SE to SMF.
On October 23, 2006, the Simple Machines Forum project was split off from Lewis Media for the purpose of " olidification ofthe team’s commitment to continuously providing free software, without the perceived risks of corporate influence". The new company was named Simple Machines, LLC. Simple Machines LLC was registered in the state of Arizona, and the transfer of copyrights from Lewis Media to Simple Machines LLC was completed on 24 November 2006 during a three-day retreat in Tucson, AZ.[
On Dec 02, 2006, SMF 1.1 was released.]
On April 8, 2007, Simple Machines announced the introduction of SMF 2.0. SMF 2.0.x has been in development alongside SMF 1.1 since December 2005.
In June 2010, Simple Machines re-formed as a not-for-profit organization (NPO) registered in Nevada. The transfer of assets from LLC to NPO was completed in April 2011 and in May 2011, Simple Machines, LLC was dissolved. On the 24th of September 2010, the Simple Machines team announced the dissolving of the Simple Machines LLC and all assets moved to the nonprofit organization (Simple Machines) set up for the project.[
On June 11, 2011, SMF 2.0 was released.]
On February 9, 2022, SMF 2.1 was released.

and uses MySQL for database management – it is built around established industry standards and is generally valued for its high security standards. The use of PHP, MySQL and the fact that SMF is freeware, helped spawn the creation of a large and relatively active volunteer development community.[
SMF is commonly deployed on basic web hosting packages, usually Linux, Apache, MySQL, PHP (LAMP) compliant servers. Installations on VPS or dedicated servers are usually needed for sites with a large number of concurrent users online at the same time. The number of concurrent users that can be handled depends on the available server resources, the resource limits a hosting provider may imply, the server configuration, and on which kind of modifications have been installed. SMF itself has virtually no limit of traffic it can process, however: the more users online, the more powerful hardware it will require in order to function.][
Simple Machines Forum has 4 versions, SMF 1.0, SMF 1.1, SMF 2.0 and SMF 2.1

Criticism
Even though the sources were available from the start, SMF has been criticized by the open source community for not being available under a free software

Starting with the 2.0 release the software is available under the BSD license, resolving the concerns.
