i use infCombatRess now, a good, simple,lightweight addon.
http://www.wowinterface.com/download...Ress.html#info
and i get some idea from Allez's alraidcd and bitbyte's saymassrez
send message to /ra or /p or /i when click the icon:
just like " available battle rez: 0 , next battle rez: 1:35" etc.
also, when someone use battle rez in group, addon will send massage to group channel: "battle rez: OOO to XXX"
is this possible? or some other lightweight addon can do this?
