That's up to you. It's your server, after all.
I'd suggest removing it, since it's pretty much outdated at this point.
Since TheWizard refuses to remove my old (incomplete) files from IEGMC, people will still have full access to old versions, sadly.
Unless you've been a jackass towards him, I have a hard time believing that the Wizard would refuse to help you. I'm not trying start a fight with you, btw; I feel compelled to respond because I've never known the Wizard to be anything but friendly and helpful.
If you have been an ass towards him, I'd suggest apologizing to him and being very, very polite when asking for updates.
