I'm pretty new to RPGs in general, but after playing D&D 5e with a roll20 group for several months, I've started to DM a mini-campaign in roll20 for the odd week our DM can't come. However, I'm looking for a good place to sound out encounter or campaign ideas. There's one or two people in the group who could do that well, but then I would ruin the surprise for them. (a) Is this a suitable topic on one of the roll20 forums? (b) Is there someplace else to float D&D encounter/campaign ideas?
