New Post: Twitter lists members only returning 20 users

Hi again,

I've noticed that TweetList.GetMembersOfList() only ever returns at most 20 members of the list, even when the optional parameter is set.

I'm using the following code:
TweetList.GetMembersOfList(list_id, 500)

The list I'm using as an example has the ID 48814195 and currently has 418 members.

In the output console the GET request has the URL with cursor=-1, so is it only getting the first page and not the full members list?

Regards,
James
