Well, that depends if you want to take a run @ RB or not. If not, then by all means chop the posts for FREEBIES altho MATT is correct...going by posts made over a summer weekend is not a good judge of the volume that freebies post. When I started here, FREEBIERS were only allowed something between 5 & 10. You & Matt implemented a bonus scheme for FREEBIES based on new members joining up or some such thing & iHub settled @ 18 posts for FREEBIES. At one time this increase to 18 posts/day was to be for a finite period & then revert back to the 5 or 10 as it was originally. I think it was a wise move to keep it @ 18 as giving something for free is always good promo; taking it away later...not so good promo. So IMHO, a good decision was made to leave it @ 18.
Having said all that, if you truly want to take a run @ RB and ultimately increase your revenue stream by signing up premium members, IMHO, you will have no choice but to give unlimited posting on stock boards to FREEBIES. Only then will you be able to attract the volumes here based on the speed of the site & other FREEBIE features from which you can convert them to premium subscribers. The trick is to get them here in the first place & you need a carrot ie unlimited posting on stock boards only. Once they are here then you can "work" them into the value added features. I know that you don't see it that way & perhaps you don't want to take a run at RB and that is also OK but you got to do something to get the masses here & FREE works to get them here.
IMHO of course
