Wow, thanks for all the suggestions! You guys are awesome!
@PrimaThemes @WebDesignPlanet Can’t use tick icon because it is used for another action/status on the site.
@fawn thumbs up – thanks to facebook, I can’t use that.. a beer/drink… there is an action called “cheer” on the site which we are using a smiley face.
@JamiGibbs handwave = goodbye? 
@revaxarts …
@FamousThemes hmm.. this make me think of using the “TQ” text
@readactor hand sake = deal, no?
@damojo I post a need/help, users answered/help, I ‘thank’ them. Oh, I try that, because the thank you is from my heart
But the client says it sounds more like ‘love’ or ‘likes’.
@freshface yes, that’s bit too much 
@rocketgraphs Interesting, I will try to implement with ‘TQ’ tho 
Thanks everyone! I love this community, really!
