Welcome.
Might I politely suggest getting your feet wet by following a few different threads before jumping in with both feet? It will help you understand the both the tone and tenor of the various threads, what is taken seriously and what devolves into puns and laughter, and what the (too numerous to mention for away fans) faux pas are in posting.
Good luck! If you are open to a bit of back and forth and an occasional “fuck you” or the ever popular “Rag” for any comment even remotely critical of certain things, yet reflecting anything positive on any other team, you’ll do well.
Oh, and if you don’t live in the UK, tread carefully, because foreigners don’t know fuck about football. I know because I get told repeatedly, even though I’m from Manchester!
Happy trails…
