The Indiana Jones Subforum was a forum created to host side-conversations not directly related to the LEGO Indiana Jones theme. Over time, it became mostly a roleplay subforum, but it had many discussion topics as well. The most popular topic was the Silver Hawks HQ 2, led by JohnnyNeutron, a very popular roleplayer. The Silver Hawks HQ had over 180 pages. The first HQ on this forum was created by Finckboy. The forum had just under 10,900 total posts and 70 topics.
The Indiana Jones forum used to be quite popular with its many roleplay topics. Before its deletion, it became one of the more less-visited forums, so moderation there became slower. It became a subforum in the Classics Forum alongside other discontinued themes on October 8, 2011. It was deleted alongside the Ben 10 Forum.
