I've been asked recently by a couple of folks about the ability to share relevant documents with others on the forums. Makes a lot of sense to me!
Although I'd love to give everyone that ability, I think a fair balance of functionality and protection against spammers/viruses is required. I think it's reasonable to conclude that most Premium Members are NOT spammers, all premium members now have the ability to upload and attach documents.
I hope that proves useful to many.
