I was thinking about possibly setting up a review forum so members can give their reviews of harmonicas and harmonica related items. Would anyone be interested in this section? Is their anyone who would write any reviews of their own items?

I'd be interested.
I'm new to Harmonica and I could use advice on what Harmonicas to buy

It's a good idea too.
There are some different topics that sure would be interesting....
Harps!
What harps we use?
Reflections about them?
Recommended harps for beginners or for styles of playing, or what keys to get...
Recommended places to buy them from...

About artists....
opinions and reflections on newly released recordings
opinions and reflections on elder recordings .
Recordings or "licks" we love.

Harpbooks,tutorials and stuff.

Links....
Good sites for people like us...

I think most of those would make better threads then forums. Anyone has the ability to start a thread and I encourage anyone who wants to talk about something to just start a thread.
