Your other post is on page three after 5 days - that's part of the problem: lots of "unknown to the forum" people dropping tracks after very little activity within the forum or BBS on their own part.
Then there's having the stuff on Mspace - that's a turn off too as LOTS of people droop a link just to get HITS on their Mspace counters.
Add to that the fact that they're old tracks - not current and a few folk will wonder why they should bother.
Then there's the time of day/time zone factor - it's an international forum but many regulars are on the American continent.
I'm not implying that you're any or all of the above, just that there are multiple factors at play - I've had tracks up that, despite being reasonably regular, have only attracted 3 responses.
Record something newer or remix something from your older stuff, get a soundclick or similar account sorted for better sound quality, get active within the forum and she'll be apples.
I have no bias against country but, due to the plethora of posts of late, I have been more selective in who I listen to - you slipped by I'm afraid. Nothing personal, sarcastic or arrogant involved.
Now, I've checked out your forum involvement - you've not offered comment, feedback or criticism of anyone's work in the mixing clinic to date so it follows that no one really knows/knows of you. Reap what ye sow I think is the appropriate minimalist phrase. I hung around, read a lot, began to comment then critique and finally offered something when I felt I'd established some sort of rapport and had a feel for the tone of the regular correspondents - I'm old fashioned I know.
You need to take in your own lead line: "let's work together" you don't lead with "what can you do for me?" though that is the tone as you finish.
