Yepp correct you can choose any name you want
Nice! Missed this one.
@zulzedd: do you know what the reason was? which action solved your problem?
Looks like after i updated BOINC manager datadir and appdir pathes changed, so i specified them in gridcoin.conf. Now my configuration file for wallet looks like this (Windows 7 x86):
server=1
rpcuser=zulzedd
rpcpassword=my_pass
rpcallowip=127.0.0.1
rpcport=9332
poolmining=false
cpumining=true
email=my_email@gmail.com
suppressminingconsole=true
closeconhost=false
Project=489***
UpdatingLeaderboard=false
boincappdir=C:\Program Files\BOINC\
boincdatadir=C:\Users\All Users\BOINC\
Now i'm adding new projects and configuring pool mining.
