[Rsiena-help] Possible error with multi-core estimation in rev. 119

[Guido Conaldi]

Dear Ruth,

First of all, sorry for the long delay, but the home server I usually
use for my analyses was down and I only recently managed to revive it.

I have just tried to access R-forge both to test the latest revision and
to prepare for tomorrow's seminar, but the RSiena repo seems to be down.
Is it a problem from my part? R-forge seems to be up and running.

Regards,
Guido
