As the help text below it says, that's specifically for EA Profiles (which are the profiles at that link). It'll only accept a link to one of those; if you don't already have one, you should create one!
To explain why I downvoted, I don't like this general kind of response (i.e. "shouldn't this be part of large organisation X?"):
The EA Wiki would be a better place to put this, among other reasons because then everyone could keep it updated: http://wiki.effectivealtruismhub.com/
More concretely, GWWC staff right now pursue several channels to growth that wouldn't happen without them:
Speaking to interested people one-on-one (few join just from written content alone; being made 'the ask' is really important) Fostering chapters (e.g. giving them materials, arranging pledge drives, encouraging them, doing events) - most of this wouldn't happen otherwise. Seeking press attention to get new people involved - ditto, mostly wouldn't happen otherwise.
Does GWWC have rough estimates of how many members each of these channels lead to? Or could you or other CEA staff hazard a guess, even rough?
Unfortunately, the measurement and metrics around EA are quite weak and have not yet been brought together. We do not, for example, have numbers around how many people are EAs (no matter what definitions we use), any understanding of total exposure, etc.
We could improve this by getting as many people as possible to take at least a first page of questions or two on the annual EA census. Among other things that helps establish a lower bound number of people who are EA's by some definition and their basic characteristics. I remember that around the time th...
Isn't Charity Science Canadian? Organisations like that and GBS in Switzerland seem to have an advantage in that (domestic) donors often have to give through them, whereas in their home countries the charities strongly prefer donors to give directly to them. That's not particular replibable though, though donation matches are more so.
Surely anyone save an absolutist non-EA (non-consequentialist) libertarian would grant that; but equally, surely it does make sense to move lots of medications down a notch on the restriction scale. See Slate Star Codex on the FDA, 23 and me, meds with tiny chances of huge harms compared to antidepressants with high chances of libido reduction, etc.
More precisely, it was started by a student who came to volunteer in Oxford one summer, had the idea and then created it over that summer and afterwards as his brainchild, fundraising to start it as a staffed-up charity, etc. CEA hosted a number of students who came to do volunteer work over summers and other free periods. So while it was labelled an 80,000 Hours project, it's appropriate to use it as an example of someone with little relevant experience starting a charity.
