I don't tend to go by first come first served, though hate rejecting people.
For those interested please post letting me know that you:
Can and will post at least once every 2-3 days (in general).
What content (non-consensual/extreme) you are comfortable with or unwilling to roleplay.
A brief character concept (archetype and maybe a bit of background, preferably not too detailed so you can work with the other players to link the characters).
Generally, now that I'm a stay-at-home caregiver for my husband, I'm capable of doing the posting rate. You'll find I'll often post multiple times a day, miss a day, post a bunch or just get 1-2 posts a day, things like that. So long as things are engaging and there are people to engage with, posting is pretty frequent.
As for content, as some around might know I've done everything from the harshest non-con to liches and dragons and fantasy creatures to body mods (this is Shadowrun so Cyberware, Bioware and Geneware are expected), slavery and corruption etc etc. My lines are usually drawn at PC Snuff (of course if they make a mistake and get shot, hey this is Shadowrun), Hard Vore and Gore, kids and scat. Pretty much everything else is fine by me, though if it's all just 1 thing over and over it can get boring. This is for fun, and some nice variety would be good. Mad scientist wants to use someone SURGED that displays animal traits, breed them with hellhounds, plug them up, chain them up then amuse themselves for a week with whatever is available then see what the results of the breeding is? That's completely fine. Lol
Character concepts I have a ton of. Of note however are:
1) A 'Ghost in the Machine' AI who lives a life inhabiting a lifelike pleasure drone. Formerly a bland wageslave in life, she uses her new found life of immortal beauty to indulge herself in extremes (knowing that she can't die) which includes risky shadowrunning.
2) A rigger, formerly of Ares Macrotechnology, who is obsessed with Simsense and breaking into emoting/acting in Simsense movies. Think your typical aspiring movie star running away to Hollywood trope. But to help earn her money, she fixes up an old Limo and does specialized escort work (she was formerly a driver for Ares) where she plays Bodyguard and Escort while driving her clients to events etc in addition to her normal shadowrunning.
I've other concepts, like a young human scientist (all that needs be said is I've termed her as "The Daughter of Iron Man") that does what you'd expect given that title. There's your typical SURGEd runner as hinted at a bit above and a dozen more. Pretty much if there's a team niche that needs filling, I have a character to fill it.
