Hi Pedro,

Yeah, sure, pgRouting is connected to PostGIS, PostGIS is connected to
PostgreSQL...
I'm not talking about making borders. If PostGIS people don't mind
about having those questions here - I don't ming either.

I just thought that for users and developers of pgRouting (which is
tinny little project) it is not really convenient to refer to a
mailing list of such huge project as PostGIS in case of any troubles.
I also feel lonely if nobody writes to my mailing list and forum :)

Anyway, it is off topic.

Anton.
