No end no end, as Iztok Mlakar would say.
Anonymity is part of the internet, like it or not. Complaining about nicknames is pointless and it's unfair to crown everyone behind a nickname a coward now. Many people can thus actually express their opinion, which they might not in public. That's the charm (and problem) of forums.
I have nothing against Igor, but I think that even 100 years of experience in hiking, alpinism and mountain rescue doesn't give you the right to look down on others or comment on every little thing someone writes not exactly according to your pattern (sorry, but that reference to "experts" was just as completely unnecessary and provocative!).
In the end it's all meaningless anyway because no side wants to give in, so every bickering is doomed to a barren end and it's only right that the admin deletes such things!
My 2 cents.
