Ah thanks guys.
Its not a issue on privacy as I they hardly even add me so that not the problem. Its just getting invited all the time that annoys me. Like as soon as you leave one second later you end up back in there and when you try to leave you just wind back up in there until you sign off for a while (or hide by using the appear offline status). Maybe one day Microsoft will add the feature like Yahoo has had for years. Although I wont hold my breath on that.
I'll try what you suggested matty and Cookie.
Okay Conversation Warning is no longer in the scripts database so thats one down neither is Messenger Discovery. I'll take a better look and look harder as I should be able to find it somewhere. Actually I really did not look at the page that I opened of the web site for Messenger Discovery. I only realized it after I Google'ed it
btw what a sweet addon. works well and has a lot of options
