<br>
To be honest I am not quite sure how to respond to this, without stepping on someones toes. <br>
But here it goes.<br>
<br>
You are aware that the DX-Cluster system is also used by casual users, who couldn't care <br>
less about bandmaps, contests and what else?<br>
<br>
DX-Clusters have been used just fine for 30+ years, without the use of RBN.<br>
<br>

<br>
That is some statement. So what you are saying, is that all DX-Clusters without RBN feed <br>
might as well close down? I mean since they are of very little value.<br>
<br>
RBN is probably a good thing for some. But the user can turn it OFF if the user don't want it.<br>
<br>
I don't know how much RBN spots are used on various DX-Clusters. I can only speak for <br>
OZ5BBS-7. I have an average of maybe 45-55 users on a daily basis. Not many of them have <br>
enabled the RBN feed.<br>
<br>
I doubt that the casual user of a DX-Cluster wants to get a DX spot of some W station spotting <br>
itself 930 times during the CQWW contest.<br>
<br>
Its like everything revolves about contesting. Thats not the case.<br>
<br>
Many users who use DX-Clusters, couldn't care less about contests.<br>
<br>
I am not saying that DX-Clusters shouldn't evolve, and we should be stuck at how it was 30 <br>
years ago. But, it should be done with the casual DX-Cluster user in mind as well.<br>
<br>
I hope I didn't step on too many toes here :-)<br>
