Because all the cool kids are OOCing for the newbies these days 8)
There is an NPC school nurse who staffs the school infirmary during normal school hours. Your character can feel free to handwavily visit her for basic medical needs (bandages, aspirin, condoms... ;) )
Fandom Town Emergency Clinic, or NAMBLA FTEC is where all townies go, as well as characters with major medical needs and/or the desire to RP out medical care. It's staffed by doctors, students with some sort of healing/medical experience, Tommy Gavin who has first-response training, and an NPC nurse who helps cover all the gaps.
The NPC nurse is always on duty regardless of whether or not the clinic post mentions it. Townies or anyone else who want to handwave medical care are free to use her without asking permission. Medical care that is RPed is covered by two shifts, day and night, and the schedule is always updated at
fandom_clinic's userinfo so you know who's on staff. In RP time a general rule of thumb is that if it's before 6pm Fandom Time your character uses the day shift, if it's after 6pm Fandom time they should go to the night.
If you know in advance that a huge medical problem is coming up (this would include long-term overnight stays and RP events that will result in multiple characters showing up at the clinic at once) please please PLEASE contact either me or the person on staff that shift to give them advance warning. That way we can schedule extra hands to help, make sure the clinic's got the supplies you need, etc.
Finally, if any of the new characters would like to work clinic shifts you can let me know in the comments and we can make arrangements for Tommy to interview you. No guarantees on getting a job until we know what your character can bring to the party, but can't hurt to try =)
