Hi,
I wanted as many others to use WoW-roster for an alliance of two guilds. I found that there is no native support for this.
I did setup one separate WoW-rosters for each guild. I then let our members upload data to those rosters.
Then i created a third roster which I named Optimus, that is the name of our alliance.
I then hacked together a SQL-script that merge the two first databases and put it together in the third, I let this script run nce every hour.
Dunno if this will help anyone but it works for me =)
I have all tables in the same database and use the following prefix's
roster_ = guild1
roster2_ = guild2
roster3_ = Alliance
Change the first INSERT row to match the name of you alliance and realm...
The script is attached to this posting...
