This isn't anything i've made, but its something i found and use while i run oBG so i figure others might like it while they bot.
It's called ALar Bg Helper. It has many bg features like timers and such, but the big one is i use is --->
Feature: You can automatically thank people who heals you in battlegrounds. Antispam included (no more than 1 thanks every 4 minutes to the same person)
you can d/l it Here
To set it up just install it in wow like a normal add-on, and load up the wow. When in wow type "/abh gui", the guid pops up, click the general tab and make sure "thanks people that heal you" is clicked on, thats it! Now when you get healed is should Emote "you thank *target*"
Simple, but i thought it was cool.
thanks alar! :wave:
