Isitlyme, sorry your dad is going through this. I leave it to others with more knowledge than i, to offer advice.
Regarding logoslidat, he is a good guy with good intentions, but always states what is on his mind, and "tells it like he sees it" so as was already mentioned, do not be offended.
If his posts are upsetting you, the forum as an "ignore" feature, and if you go to one of his posts, and click on the word "options in the upper right corner, you will see a drop down menu, and one of the choices will be "ignore logoslidat". If you click on it, you won't see any of that members posts any more (although if someone quotes one of his posts, you will see that).
No problem Prato and thank you for your help. I just thought that logslidat was angry or so. We should be angry to those who misstreat us.,,
