@joker_josue You need to set TalkImg.com as your avatar and signature! Seems crazy to not use those spaces and your reputation to promote TalkImg all around the forum.
I doubt it is needed as of now as TalkImg has grown organically through discussion and a lack of support from Imgur. At the moment TalkImg does not have any monetary support and if the owner wants to get some revenue through a signature campaign then I do not think that should be an issue. I do feel after a certain period of time TalkImg should introduce an advertisement revenue model. When it is done then that would be the right time to utilize the signature space for promoting TalkImg.
