I adjusted some settings on our end to try and fix the cookie conflict, but it may still be necessary to clear your cookies again. If anyone's still having login issues (and the steps Helm posted above aren't helping) either post here or send me a PM, I'd really like to get this resolved for you all

edit: some updates:
About the spell checker: I had to contact the host for the access to get this one fixed. Hopefully they'll give me a timely reply so that I can move on it.
Quoting: This seems to have been fixed with some of the other repairs I was making. If anyone still has problems, I'd love to know :p
