I fixed most of maintainer tags. (hope I did not mistake and did not add myself to foreign package))

Moreover he seems to not have notification for comments for his packages in the
AUR, so writing a comment about a package is like writing it in /dev/null.

Current AUR sends notification to owner even if he  was not subscribed.

The last thing: seriously, who the hell needs stuff like
cross-arm-wince-cegcc-libstdcppdll ? More than 500 packages owned by sergej have
less than 10 votes, so virtually useless.

People who have PocketPC and want to write program for own needs want to have cegcc package group. Yes, I don't know how many people want it...

I have to admit almost all his packages are not out of date (still, I can't
understand how this is possible), kudos for that, but IMHO the quality is
more important than the quantity.

 
Quantity becomes quality
