RLUG stands for Romanian Linux Users Group.
RLUG is the largest and oldest Linux community in Romania, formed around 1999, with more than 2000 members subscribed to the main mailing list.
All services are free and offered by volunteers, as is common among all Linux user groups and other Free Software communities.
The community is sustained by its members (through hardware, financial donations, services) and by two of the main ISPs in Romania: iNES and GTS.
More information can be found (and added) on the RLUG Wiki on the official webpage.
