hello.
first of all, are we talking about a module for anope, or for ircd?
asking because of "as it is no longer possible to install Unreal3.2.7."
secondly, unreal 3.* is outdated, there is no support for that.
----
i am not familiar with os_staychan.c; didn't even find it on the modules page.
based on it's name, i could guess, but i really don't want to, so could you please describe what it does?
perhaps there are already such features in the latest version of anope / unreal.
