Some of the members of #conlang on Freenode have started a project similar to Conlang Learners ( http://www.frarathwiki.com/Conlang_learners ). Members so far are cntrational, SF|008, vragnaroda, Fenhl, Ienpw_III, and bornforwater. Proposed conlangs so far are Kala, Sandic, and Rejistanian. Until 2011-10-25, you can join the project and propose conlangs to learn. Just join #conlang-learn on Freenode (link: irc://irc.freenode.net/conlang-learn ) and follow the instructions in the topic.
