Your question is confusing at the start. When you say "site" , it could be the website Social Rabbit plugin is installed or the social media sites Social Rabbit is posting.Did you mean social media sites or your own store websites? I have social rabbit and currently it supports Facebook, Insta and Twitter- that's what it's designed for.
No, it's not obvious
Yes, it could be. There are many here in the forum, only the writer understand what he write. Before I publish a post, I always imagine myself as the person who will read it, if I can understand it and clear. I never imagine myself as the the person who will read it, of course I understand it, it is mine.Not to you "apparently" ... lol.
@Humantorch and I had no problem understanding the question. Anyone who has the slightest interest in Social Rabbit would already know it works with several social media sites. Simple logic. Actually the idea that he was referring to "How many Social sites" never even occurred to me ... or @Humantorch
Unless you're just being pedantic on purpose.
