By allowing a custom name the excellent functionality of the classroom area could be used to create other interesting spaces like a dedicated High-Quality Blog or E-zine. In addition, many communities have strong themes or non-course related offerings so being able to add a custom name to their specific place of learning or unique offering would help create the desired atmosphere/ambience for the group. Think "Training Grounds" "Apprentice's Workshop", or the "Vault of forbidden knowledge". The default would remain classroom (or courses). let me know if this is something others might want?
