Is there a way to do a character count instead of a post count. So maybe it can show instead of "Username: 540 posts", maybe to read "Username: 10,546 charaters". Can this be done?
It's doable, by checking the post string length and record it to the database, on a new column or using the preexisting postcount column in the Members table.
If you're not really familiar with PHP coding, you can post it as a mod request (http://www.simplemachines.org/community/index.php?board=79.0).
