Official support for phpBB2 ended on January 1, 2009, and the 2.0.x support forums have been locked. Furthermore all development for phpBB2, including security patches, has ceased as of February 1, 2009. However, a number of unofficial support sites for phpBB2 have formed to fill the void.
Many administrators still prefer to run phpBB2 because it provides a much simpler administration interface and has a thriving ecosystem of MODs (modifications) and styles that allow admins many options for customising the software to their liking. Others still run phpBB2 because they have installed many MODs, none of which are compatible with phpBB3.
The default theme in phpBB2 is named subSilver, and was designed by Tom "subBlue" Beddard. At the time that it premiered in 2001, it was a revolutionary new design for bulletin boards, and many bulletin board themes since have borrowed many cues and design elements from subSilver.
