Be honest and share about you whether you post only for your signature requirement or you post because you are involved in gambling & you want to know or share knowledge.
From all gambling activities, I'm only in poker and in sport betting (only football betting and only when i know teams, championships and so on). I like to talk about interesting topics, which is related not only to poker or betting, but yeah, i think a half of posts here is for signature.
There not so much topics about poker
^ Probably there are a lot of poker topics and it won't bring a good discussion, same as you, I also love to hear discussion about poker which is I am good at this kind of game. But poker discussion is not necessary because there is no update on this game not like betting and other sports games there could be matches that we need to discuss. For me, it is hard to join a gambling discussion for the sake of your signature campaign, you must experience playing and gamble and then you have an experience there is probably a chance you will not be off-topic and make an awkward post pretending you are that gambling games.
