No, the DMsGuild is website run by WotC and the DTRPG people. You can create an account and post your custom D&D content for people to buy (and free or pay what you want are options). You can use anything in the Basic and SRD and, DMsGuild only, Forgotten Realms and Ravenlofy IP. You can check it out here: https://www.dmsguild.com/
Oo right, heard of that place, could just not connect the name to it.
Well, I guess that could be fun. Selling I think is out of question since a lot of the images I used are copyrighted, but for free can't put me in trouble I think. There was no such plan, but if you guys says it might do good for others, then maby I should consider it.
Judging by the next comment though, the DMsGuild will own the content after uploading? Or why would I have to delete the file from this site?
