Can I search buddies at another realms?

I am playing on russian realm and was wondering if anything can be changed/configured in OQ to be able search across other EU servers, lets say English ones? Or I am locked in my russian servers only? I am still angry on blizzard for knocking-down OQ. In the mornings russians are sleeping, however many groups from EU were available through OQ before 6.0.2 and I would like to continue playing with them. Thank you Tiny

I have 2 problems.

1st - my GMT in OQ is different from my time zone and even server time. How do I change OQ GMT?

2nd - My FIND-MESH button is just grey and cannot be cliked. What do I do in this case?

Thank you.

PS I played WOW because I had OQ. If it does not work now nad will not work in future - I think I will quite WoW. I was online from the beggining (ouch - it's been many years!) but lack of OQ depresses me.
