[drupal-devel] New module nameing.

I've written a new module and would like other module devels to give me their opinion. This module allows editing of the help messages for any page on a drupal site from within the administration pages. Right now I have it named "helpdb". From a technical point, sure the name describes that it adds a database back-end to the help system. But, its not a pretty name. I was thinking maybe "help_edit". What do you guys think? Are there any conventions to nameing modules other than all lowercase and underscores instead of spaces? I see in the current module list that some patterns are emerging (like taxonomy_ and node_), but is anything enforced? Thanks, Aran
