I'm reluctant to put a reference link up to a more visible place, because we (the coppermine dev team) have no control over your site, so we can't say for what purposes the information gathered there will be used. We have trusted others in the past who volunteered and created what appeared to be a coppermine-contribution site, and we have put a link on the coppermine home page to tell people about the "service" the other site was offering. The person who offered the "service" on his site then added malware to the site once we had the link established - we only realized this after some time, as we can't check external links every now and then. Anyway, this damaged the reputation of coppermine, and a site like yours could be used to damage the reputation of coppermine permanently if used in an improper way.
Don't get me wrong: I'm not accusing you that you're doing something wrong, you're probably only trying to be helpful and help improve coppermine. However, as explained above, I don't want to create the impression to others that the coppermine dev team has any influence or say on your site, that's why I won't post an ad for it in a better place.
Recommendation: add a link in your signature on the board that pints to this thread or even directly to your contribution site - this is advertisment that is OK for us. Encourage others to do so as well.
Another option would be to give us your code as contribution, then we could make up our minds if we wanted to host the contribution site, this way keeping control over it.
I hope you can understand this and don't have hard feelings - it's just that I've seen to much fraud happen with contributions like yours in the past.
