My name is Ezinda and I'm one of the forum community team.
Thanks for your question.
Of course, when we set up the Northeast creative corner, we did realise that a forum is fundamentally a space for written communication. There are limitations, of course. But that just means we have to get more creative!
Visual artists including photographers have shared their work here. I’m familiar with a few tools for doing this including http://www.flickr.com
where you can upload your pictures then post a link here for others to share it.
I also know that others on this site, including edgydonkey, have used different tools to share. Could anyone recommend another site to maker?
As for musicians, hmm. That one might be a bit more complicated. I'm not a musician myself but if someone would like to share their own music, they could try something like Youtube http://www.youtube.com
or Soundcloud: http://soundcloud.com
. On both, they would be able to upload their creative output to a site and then post a link here to share.
I hope it helps!
