SepSceneWriMo is essentially an open writers’ workshop.
Anyone participating effectively announces their intent in perfecting their scene writing and critique is expected.
Of course, common courtesy must be honored.
Positive criticism, corrective hints, the ID of inside out sentences, grammar, spelling, POV issues (head-hopping), etc. etc. and so on and so forth are allowed and encouraged.
Let me say it again: encouraged.
Writing is hard. Writing well is damn near impossible. Writers need all the help they can get. Fawning platitudes are practically worthless. I said “practically”. Of course many of these scene-writing efforts are worthy of praise. So, slather the accolades if you feel the need. But if something doesn’t work for you — let the writer, us, know.
