A #mastomonday quick tip: If you're new, you may see terms and abbreviations thrown around that don't immediately make sense. Here's a handy guide:
lb: last boost
mh: mental health
ph: physical health
ec: eye contact
spoons: a way of expressing mental energy/willpower
fractela: rare (in my experience, anyways), but basically means "no context"
pol: politics (might have region, e.g. uspol, ukpol, itpol)
Hopefully, this helps you understand things a bit better than I did when I first joined
Mild silliness
Of course, you're also expected to know the standard set of text abbreviations (e.g. imo, fwiw), queer terms (including the rare ones), technology terms (you did do the training course, right?), and politics terms (like the difference between a demsoc and a socdem).
All of this knowledge should be found in the introductory textbook that your instance's admin will be sending you. If it hasn't arrived in 3 to 5 weeks, please call 1 555-555-4429 for assistance.
Re: mild silliness
To be fair, this is stuff you should know, but it's okay if you don't. You can find info on this stuff elsewhere, unlike, say, what "fractela" or "mh" are. You'll learn those over time.
