Is it OK to ask about specific products? Should we provide some guidelines on how to do so?
For example, I asked a question about the Dwarven Forge product here, which spawned both a good response from an actual user of the product, as well as some good suggestions on alternatives. However, a similar post later, discussing the Epic Words website, was attacked as being an "advertisement", so I deleted it. I still have other products I'd like to ask on, but I thought it would be good if we could get a policy / suggestions on how to phrase these kind of questions so that they're not upsetting anyone.
(This should probably be community-wiki)
