When I find I am trying to nominate a person twice in a row I just ask a DM to swing by on the DM channel, which is from what I gather, the same as waving my little green wand.
It's great that the DMs are willing to do this, but what is the point of limiting the recommend tool, if people
can just call a DM over (just to make myself clear - I am for removing the limit on the wand, not against DMs dropping

)?
I am quite happy to continue as it is, I just don't like the thought I may be annoying them or look like I'm begging for DCs.
