Toolserver Tools - Soxred93: PLURAL template necessary
Please request this feature from the toolserver guys directly. As far as I know every toolserver tool is a stand alone PHP program. I fear every programmers has to implement this feature itself. But nothing Translatewiki can do for you. Sorry.
Using PHP is not a requirement, so it can be any programming language; me alone using six different ones at least. As I said, no research, isn't there a library delivering strings to programs, which could take the parameter substitution and formatting stuff in a centralized way?
