You are connected to Quakenet? Do you think the owners of that network would be impressed with all 150,000 users sending un-necessary bytes to the server often enough to get a satisfactory resolution from a lagmeter?

I have a scripted one and I set the request/reply frequency to a fairly 'friendly' level but because this can be abused to the point where a server can be laboured by thousands of people with inappropriate settings I feel this function should not become part of mIRC itself.
