[Help, Code, AddOns] InviteMe Modification Request

[Muramasa]

Basically I am trying to have an addon that will invite people to my guild whenever they whisper me with the word "invite". I took Striph's old raid invite addon and tried to change it to accommodate guild invites, but alas I am a noob at scripting. Anyone who could send me a simple working code I'd appreciate it oh so much. Bonus points to anything that can be converted between guild and party/raid with the replaceall of just one function.

InviteMe : Outdated Mods : World of Warcraft AddOns

So far the only thing I changed was a replaceall of "InviteUnit" with "GuildInvite". It now has no functionality whatsoever.
