Since you posted this minutes after you dashed to 50 posts, the forum probably just hadn't approved you for SYW yet. However, dashing is frowned upon here, since it ignores the purpose of the 50-post limit, which, incidentally, is to allow us to get to know you and you to get to know us before demanding our time on your novel. 50
posts don't do that. For best bang for your buck, critiquing in SYW creates goodwill that might be reciprocated while helping you learn what works and doesn't work through those critiques. You'd be surprised what you can learn on your own writing by critting others.
ETA: Also, please don't submit a second thread requesting betas for the same novel. Publishing requires patience, and you're going to be very frustrated in this business if you don't learn some.
