It can be a bit overwhelming. And if you're coming at a day or more late, I certainly don't expect you to read everything on the board before you post. ;-) I think honing in on specific threads or topics that interest you is a good way to go. However, I do expect you to read everything in a thread before you post in it, so you're not duplicating another's post. Things tend to slow down in the latter half of the week, so you may be able to catch up then, if you'd like.
