I completely agree that people need to proof read their work before wapping it on the guild to make some 'easy' money... It just means no-one will buy their future work when(/if) they actually put the effort into it.
Also, I'm glad they released the 5e OGL as I've been writing up one of my quest lines for months now, (having it proof read by a writer and another DM throughout) and it's been so hard to convert some things from the 3.5e to make sense in the 5e format. I like how the DM's guild gives us a good secure place to sell our wares too, although I'm bummed out by (but fully understand) the large cut they take, BUT, the fact it costs us $2 to retrieve any funds we've actually accrued is a bit of a kick in the nads... It means my quest is going to have to cost $2.80+ (I think... my maths isn't great) to get anything out of it, which instantly makes people not want to buy it...
Meh... it's 30+pg's long and well written, so I'm hoping people will want to fork out for it =/
