Dorsal view of a Limnephilidae (Giant Sedges) Caddisfly Larva from the Yakima River in Washington

One of our registered users was recently having some problems logging in, and getting a "password wrong" error even though he had the right password. Since this is a new system and I'm still working out the kinks, I wonder if maybe this has happened to anyone else.

I have a way to manually fix accounts in the meantime. So if you can't log in, email jason@troutnut.com and I'll set you up.
