Is their a way to sort post via Alphabetical order and not date posted?
By URL: http://www.simplemachines.org/community/index.php?board=2.0;sort=subject
You can try out my mod (http://mods.simplemachines.org/index.php?mod=382) if you want specific boards to be sorted a special way without changing the url.
If it is every board, I can tell you how to edit the code as my mod wouldn't work so well requiring you to change each boards default sort one by one.
