Hi, welcome to Baccano! Wiki! Thanks for your edit to the Czeslaw Meyer page.
GP Effects + Villains Wiki Edit
This is very belated of me, but – welcome back to the wiki. I was quite surprised – in a good way – when I saw you back after over a year and then some.
There are two things I'm going to address here – one is your message on my Talk Page about the Villains Wiki (sorry it took me so long to reply to you on this; it was part forgetfulness and part a reluctance to return to the wiki); and the other is the new section you added today to the Grand Panacea's page.
Villains Wiki - Truth be told, one of the admins of the Durarara!! Wiki and I visited the Villains Wiki a while back and weren't exactly keen on it; several of the Baccano!/Durarara!! pages there were borrowing from the corresponding wikis without credit. (I believe I never got around to adding credit; I know I didn't stop to try and improve the articles). Some of the characters had been sorted into categories I'd probably call incorrect, come to think of it. If I remember right, they'd classified Graham, Izaya, and several other characters as 'psychopaths' when they're really...not.
I do remember there not being a Baccano! category for all of the Baccano! characters, which – yes – I think would probably be helpful. I'm less convinced that an actual article (is that what you mean by sub-page?) on Baccano! there would do anything to increase its visibility on such a wiki; I'd also have to check the wiki's rules to see what's permitted and not-permitted. Speaking of which, last time I was there I saw several pages using fanart despite fanart being against the wiki rules. Yikes.
Maybe I'll revisit the Villains Wiki sometime in the future to try and fix things and make a case for removing non-apt categories...but there's so much work that needs to be done on the actual wikis for Baccano! (and Durarara!!) that I really ought to prioritize said actual wikis first.
Grand Panacea - It's not that a section for the elixir's effects isn't a good idea in principle, don't get me wrong. My main concern is that it's redundant, since the article clearly states in its introduction that the GP grants complete immortality and links to the Immortals article - which already lays out what complete immortality is. If you disagree, I can leave it up and clean it up a little, then.
