There seem to be a couple problems with the forum atm (I don't stay logged in, my sig doesn't show up, couple of the tags don't seem to work, where's the spoiler button , etc.) Are these permanent, or just bugs?
Thanks for the report. Logins should now be persisted if you checked the appropriate box on the next login. Signatures have now been enabled, but will be disabled if the feature is mis-used/abused. Spoiler buttons is not supported unfortunately.
