Upgrading Groupwise

[nanu]

Hi!

My actual LAN is a tree with 3 servers 2 of them NW 6.5 SBS sp1 and a NOWS SBE 2 (SLES):
1.NW 6.5 sp1 - Border Manager (Firewall)
2.NW 6.5 sp1 - GroupWise, DNS-DHCP, iFolder, iPrint
3.NOWS SBE 2 (starter pack) - WEB site with PHP and MySQL

I wish to upgrade the GroupWise from the original 6.5 that was packed with the original NW6.5 SBS sp1 to a supported version.

My questions are:

1.Are the higher Gropuwise upgrades free for the NW6.5 SBS?
2.Where can I download the upgrade?
3.Can I post support questions in this forum or in the GropupWise formu?

TIA

Nanu
