Hi Igor,
Just wondering if the plugin had been of any use at all?
Best wishes,
Mark
Thanks for your help so far guys 
I think that the problem must lay somewhere else in the page code since no matter what method I use EE interprets all comments as from user 1.
I am pasting now most of the page code (the relevant part) since I am sure a trained eye will spot an error somewhere
