i would put him in the top 10 most knowledgeable users on the amiga.org forum.
What, like pretending to be someone else and asking people if they knew if a CD-ROM drive could be fitted to an Amiga?
Sorry, but I wouldn't take advice from him even if it were free. I've read way too many "People who modify their Amigas are idiots!" posts of his, he clearly knows very little of which he proclaims to be fact.
As for his abrasive attitude, he's upset a great deal of people and seems to thrive on being obnoxious. Mil spec humour or not, he's one sick puppy and best left banned IMHO.
