I just keep bumping this, as I have no idea whether or not theymos has seen the thread.
It seems the first batch of Merit sources was quickly processed, and since then
Merit sources have been stuck at 57 in total.
We're up to 80 merit sources at this point. That means you've got to be somewhere in line for processing. I've already given my endorsement, but it seems kind of silly that there is no way of knowing whether or not you've been viewed, reviewed, processed or rejected. The only answer you will be aware of is if and when it is a "yes". I would like some more transparency on this front, as it leaves less room for confusion and us sitting here in a daze. I imagine you haven't been accepted, because I haven't seen an increase in your merit sending; plus this thread is still open and being bumped.
The first batch(es) were probably, if I had to guess, done in some kind of order of necessity. Local-boards probably are getting priority as theymos originally mentioned. I would assume theymos is trying to spread the sources out based on their activity, which is going to make it increasingly difficult to become a source that primarily roams around the "main" boards. I'll quit my rambling, I just wanted to give my opinion on there being no notifications or information on the status of your own application, besides what can be described as an educated guess.
Side-Note, why do you think they seem to come in batches of acceptance rather than one at a time? That behooves me a bit, unless theymos sets aside a particular chunk of time to bang out a bunch of applications and always manages to find multiple sources within that pile.
