I am guessing this was asked before, but I hope you don't mind me asking it again.
Would it be possible to add a "beginner" lobby to Jinteki.net?
I probably would hang out there all the time.
It happened to me several times recently that although I clearly stated that I would like to play with core cards only my opponent had the whole cardpool and even if I ask them in the lobby chat if they have core set decks they don't reply, are confused (one guy took like 5 mins till he realised what I was talking about) or quit and are replaced within seconds with a guy with similar attitude.
Because there is no "legal" way to build an NBN deck out of 1 core set since the Astroscript errata quite a few beginner core decks are labelled as "invalid" and many Anarch decks have problems with the MWL influence points and are labelled as Casual Play only.
Having a beginner lobby could solve many of these "(first world) problems".
