I saw return string.find(text, "lfm") ~= nil or string.find(text, "lf3m") ~= nil or string.find(text, "lf2m") ~= nil or string.find(text, "lf1m") ~= nil in chat-parser.lua. Lua does have some not-quite-regex matching- I think you could pull this off with just return string.find(text, "lf[1-3]?m") = nil. Or return string.find(text, "lf%d*m")=nil if you wanted to catch raid-sized LFMs
